I am trying to tidy in my test environment and there are many apps that don't need to continue living. There are both standard apps and SharePoint forms. In both cases, I manage to enter the detail page, I see the garbage bin, but when I click it (and confirm deletion), I am navigated back to the app list... and the app is still there!! I have been trying this now for some days, and I always get the same.
This was possible before, so I suspect there is a bug here... @microsoft, any idea?
Btw: I am global admin, and I am using PowerApps though an Office 365 E3 licence.
