Presence status does not update correctly

Description

Hello,

Since the update to Synapse 1.64 or 1.65, we have the problem that the status of a user in Element no longer updates correctly. The users are using Element version 1.11.3. The problem cannot be reproduced correctly, for one user the status is updated correctly after approx. 1-5 minutes after logging out, but another user is still shown as online even though he has already closed Element for 30 minutes. If you delete the cache in Element, the status is displayed correctly, but not permanently. Has something been changed in the presence handling that could cause this behaviour?

Greetings Erik

Steps to reproduce

• User 1 is online
• User 2 sees that User 1 is online
• User 1 closes Element
• Wait 10 minutes
• User 2 sees that User 1 is still online although User 1 has Element not opened

ERROR: could not serialize access due to concurrent delete

This is fine - it just means that two writes to the database were attempted at once. Synapse will automatically retry the query that didn’t make it.
