Basically what it says on the tin. I clicked both register buttons but nothing visually has changed, so I have no clue if something went wrong or if my device has successfully applied.
On members app go to setting and you will see one ui beta program. If you click on it. It will have an option to deregister. That how you know you are part of beta.
Same here. Nobody has clue as I contacted the Samsung Care Pro and had a chat with few of them.
When your regitration is complete, a brief message "thanks for your supporr" will show. Registration banner will deissapear afterwards, if you still see it, then you are not registered.
Now it makes sense! That's means my device is not registered in the beta program.
