I've made sure -

My signing keys are the same as uploaded in play store, as I can sign in facebook and other auths methods + I've verified myself.
The Google play google shows in My apps and games tab, with an UPDATE button showing up.
Application ID is the same
I've downloaded from the Play Google numberous times.
I've tried in the Internal Test track and a closed beta release

EDIT: Also I've tried to run the app from adb install, or trying to install from google play and after that deploying aab on the play google.
