When i try to sign in with my google account it says : Sign in with google is temporary disabled for this app

Can someone help me with this?

Well, if it’s “temporary disabled” that implies that it’s both temporary and intentional. Meaning you and everybody else using “this app” will not be able to sign in with Google for as long as it takes.

If you ask me, not having to tell Google when you log in where sounds like quite the improvement. ;)
