User interfaces for managing media libraries

A non-transitory computer-readable storage medium storing one of more programs configured to be executed by one or more processors of a computer system that is in communication with a display generation component, the one or more programs including instructions for:

• detecting a request to share media items from a first collection of media items with a set of one or more users;
• in response to detecting the request to share media items from the first collection of media items with the set of one or more users and in accordance with a determination that a first set of criteria is satisfied, wherein the first set of criteria includes a criterion that is satisfied when at least one user in the set of one or more users is determined to have been present at one or more events corresponding to media items in the first collection of media items, displaying, via the display generation component, a recommendation to share a plurality of media items with the set of one or more users in a second collection of media items, wherein:
• the plurality of media items that are recommended to be shared with the set of one or more users includes:
• a first set of one or more media items that correspond to a first event at which at least one user in the set of one or more users is determined to have been present, wherein the first event occurred during a first period of time;
• and
• a second set of one or more media items that correspond to a second event at which at least one user in the set of one or more users is determined to have been present, wherein the second event occurred during a second period of time that is different from the first period of time;
• and
• the plurality of media items are recommended based on the set of one or more users that are identified in the request;
• while displaying the recommendation to share the plurality of media items with the set of one or more users in the second collection of media items, detecting at least a first user input of a set of one or more user inputs, wherein the first user input is a request to add a respective user for identification in the second collection of media items, wherein the respective user is not a user in the set of one or more users;
• and
• in response to the set of one or more user inputs, adding a representation of the respective user to a set of representations of one or more users without adding the respective user to the set of one or more users, wherein the set of representations of one or more users are used to identify one or more media items to be shared with the set of one or more users in the second collection of media items.

A method, comprising:

• at a computer system that is in communication with a display generation component:
• detecting a request to share media items from a first collection of media items with a set of one or more users;
• in response to detecting the request to share media items from the first collection of media items with the set of one or more users and in accordance with a determination that a first set of criteria is satisfied, wherein the first set of criteria includes a criterion that is satisfied when at least one user in the set of one or more users is determined to have been present at one or more events corresponding to media items in the first collection of media items, displaying, via the display generation component, a recommendation to share a plurality of media items with the set of one or more users in a second collection of media items, wherein:
• the plurality of media items that are recommended to be shared with the set of one or more users includes:
• a first set of one or more media items that correspond to a first event at which at least one user in the set of one or more users is determined to have been present, wherein the first event occurred during a first period of time;
• and
• a second set of one or more media items that correspond to a second event at which at least one user in the set of one or more users is determined to have been present, wherein the second event occurred during a second period of time that is different from the first period of time;
• and
• the plurality of media items are recommended based on the set of one or more users that are identified in the request;
• while displaying the recommendation to share the plurality of media items with the set of one or more users in the second collection of media items, detecting at least a first user input of a set of one or more user inputs, wherein the first user input is a request to add a respective user for identification in the second collection of media items, wherein the respective user is not a user in the set of one or more users;
• and
• in response to the set of one or more user inputs, adding a representation of the respective user to a set of representations of one or more users without adding the respective user to the set of one or more users, wherein the set of representations of one or more users are used to identify one or more media items to be shared with the set of one or more users in the second collection of media items.
