From what I've heard another beta is around the corner to hopefully deal with the current bugs people are experiencing but if your sure then you can use that to withdraw from the beta best of luck
From what I'm told it was only meant for a selected amount of users and it would have been located on the main screen of this app right under Samsung rewards and right above community it would have been right in our faces but it must be already closed or we are just not the lucky ones as it is in beta only unfortunately
So it's a closed beta then. That's unfortunate, coming from Apple land where it's open to all. And where they actually update their devices for 5 years. Oh well, we tried. Guess I'll hang out and wait for the official release next year then. Cheers.
