Cannot update or delete tenant app in Microsoft Teams - microsoft-teams

Question

We have a Microsoft app which we created, installed on our tenant (tenant app, not sideloaded).
I cannot:
Uninstall the app
Update the app with a new version number
I have all permissions to do so and my account is the installing account.
The manifest was built using App Studio.
I also have a related problem: the app is still usable even though it is not installed in any team. The app does not appear in the "Personal apps" tab or the Applications tab when clicking the three dots in the left side panel of Microsoft Teams.
