Users shown as online when offline

Description:

Four of the users in my workspace are always shown as online (i.e. with the green light) even when they are not and all their devices are turned off. This also means they will never be notified on mobile, as the server thinks they’re at their device when they are not.

Steps to reproduce:

unknown

Expected behavior:

The user's status changed to “offline” when their app closes.

Additional context

There are no errors in the logs, and I have no idea how to solve it. It started a few days ago, after the 4.5.2 update. Thanks.

Relevant logs:

There are no logs hinting at any issue.

Start by investigating the server-side user presence handling introduced or affected around the 4.5.2 update; the report provides no file or test entry point. Reproduce the stale online status if possible, then verify that closing all apps changes the user to offline and restores mobile notification behavior.
