Quickly fix new Teams messages not showing up

Issues

I encountered some issues with new Teams:

• New messages do not show up
• Messages aren’t getting marked as read even when I open the chat
• I can’t send new messages

These problems are specific to the new Teams; the (old) Teams works perfectly. I attempted to resolve the by reinstalling Teams and clearing cache from the ‘%appdata%\Microsoft\Teams’ directory, but it seems these methods only impact the old Teams and the issues persist in the new one.

Solution

I found out that the cache for the new Teams is located at:

1

%localappdata%\packages\MSTeams_8wekyb3d8bbwe\Localcache\Microsoft\MSTeams

I deleted everything in that directory, then restarted my PC, and all those issues disappeared.

Conclusion

It appears that the cache directory for new Teams is consistent (at least for now). The cache directory can also be accessed by clicking on Settings -> General -> About Teams -> Third Party Notice -> Desktop.
