Hi maceyr49671160
As far as I can recall, Photoshop Sketch has always required a login but you may have been logged in to another Adobe mobile app, perhaps and it has used that token for authentication. Maybe someone from the team could clarify if this is the case?
Is it possible that you were signed into another app with a different Adobe ID to the one you used the other day?
If so, try signing in to the URL that KoMaruyama provided above, and you should find them there. You can then share them with the ID that you are using now.
Hope that helps.
