Error linking Adobe Sign App with Google Drive account

Hello!

I'm an user of the Adobe Sign app on an Android phone. I used to have my Google Drive account linked to the app; but, a few days ago, the accounts stop working togheter.

I've tried several times to link them again, but it did not work. I've also tried to reinstall the app, clear the cache, etc. No way... I can´t link my Google Drive account with the Adobe Sign app again.

I can link Document Cloud, Dropbox, etc... but not Google Drive.

Any suggestions? Thank you!
