On registeration I simply copy/ paste my IMEI number on the sansmy Registration site it there tells you if you're already registered...
Go to settings- search- IMEI- copy to clipboard- back to registration site- paste it on.
@TamerDRG89 so is mine but IDK if I can go without/reauthorize some of my stuff on the phone that I need while I'm here that's linked to my Samsung account. It's nice to have a possible answer but I don't know if it is a work around I can do atm bah
I solved this. Just force stop members app then delete cache and data and then relogin. But give it all the permissions it asks for when you login. Then once logged in, check for updates. I am US unlocked btw. No need to make new accounts.
I had the same issue and after clearing the app data like atleast 10 times did not help, I removed my Samsung account from the phone and used my college email to register and it registered immediately.
