Expected behavior

I was hoping to find my apps after the migration.
When activating Mail it should activate the app
When clicking "download and activate" it should activate the app

Actual behavior

Mail was disabled during migration (after causing an error during migration)
Upon reactivation, a prompt appears saying An error occurred during the request. Could not process the request.
When I deleted and reinstalled the app, the same warning appeared after downloading the app.
