2. Log in on the desktop app and the mobile app
2. As another user, send the first user a DM

can you give me access to an MSI for this release and we will test?

Placing in Resolved again so it remains on QA's radar for 4.5 testing.

hello it is an rc version, should be quite stable, but it is the first release with all the bug fixes, so there is always the chance that it contains any unexpected interactions. After all, that’s the reason we release at least an rc before final.
I’d suggest you keep using the msi, none of us have been able to reproduce the problem, but hopefully the fix will address it or at least make it more manageable, so making minimal changes is much better in order to know if we definitelly addressed it.
