The Matrix spec /sync API is designed to be called continually in a long-polled fashion. Can you expand the File column and take another video to check that the since token is changing, often it only changes by 1 digit. If it is then that is working as expected, your server just has a lot of data to send you, this can happen if presence is enabled due to a Synapse bug - matrix-org/synapse#16057

@t3chguy Looks like request and response is same for all requests. Not a single bit of change.

@t3chguy is there a solution for this issue or the issue is still open?
