Teams Tabs in all Channels not visible (Client)

[upfaffer]

Hello,

some users face a issue from time to time. For them the Tabs in all Chanels in the Teams Client are not visible. A App Restart helps for a while.
This issue does not occur in the browser.
Its not a permission issue....

Any ideas?

I experienced this today... had to switch to another option like for example Activity and then go back to Teams and the tabs returned...
