"Sorry something went wrong with adding the app. Click to retry"

Question

I am unable to remove the app, it is corrupted. Can any give example using PowerShell how to uninstall the app?

Answer 1

You can remove app using following powershell command

$instances = Get-SPAppInstance -Web <URL>

$instance = $instances | where {$_.Title -eq '<app_title>'}

Uninstall-SPAppInstance -Identity $instance

replace <URL> with site collection url and <app_title> with title of the app you want to remove
