Unfortunately I am experiencing a terrible bug at the moment. A couple of days ago, I bought the new Google Pixel 6 and after logging in with my Google Account, on Google Photo there was no one of all my pictures. The only thing appearing in the app is still the message "Setting up your phone library". On top of this neither the backup of the new pictures I'm taking is working since the app is saying "getting ready to backup". I see many people having the same issue and I expect an update soon
