Dynamic teleconference content item distribution to multiple devices associated with a user

A computing system, comprising:

• one or more processor devices;
• one or more tangible, non-transitory computer-readable media that store instructions that, when executed by the one or more processor devices, cause the one or more processor devices to perform operations, the operations comprising:
• receiving, from a first computing device, a session join request indicative of a request to join an active teleconference session hosted by the computing system;
• making a determination that the first computing device and a second computing device that is currently connected to the active teleconference session are both associated with a first participant of the active teleconference session;
• and
• based on the determination, providing interface display information to the first computing device, wherein the interface display information comprises instructions to display a first candidate content item of a plurality of candidate content items, wherein the plurality of candidate content items comprise one or more content items being displayed at the second computing device, the one or more content items comprising the first candidate content item.

A first computing device, comprising:

• one or more processor devices;
• one or more tangible, non-transitory computer-readable media that store instructions that, when executed by the one or more processor devices, cause the one or more processor devices to perform operations, the operations comprising:
• providing a session join request indicative of a request to join an active teleconference session to a teleconference computing system that hosts the active teleconference session, wherein the session join request comprises information that identifies a first participant associated with the first computing device;
• responsive to providing the session join request to join the active teleconference session, making a determination that a second computing device that is currently connected to the active teleconference session is also associated with the first participant;
• based on the determination, exchanging messages with the second computing device, wherein the messages comprise information descriptive of one or more first content items currently being displayed at the second computing device and one or more second content items currently not being displayed at the second computing device;
• and
• based on the messages, causing, at the first computing device, display of
• at least one of the one or more first content items being displayed at the second computing device.
