If you've done a Samsung beta before you (should) already know that during beta Google Pay will not work and that Good Lock will not be updated to functioning until after the beta ends. I've done 4 or 5 betas in the last few years and the above is standard.
Also, it's beta software, the entire purpose is to flesh out bugs so they can be stomped.
I knew all this going in so I have no complaints about any of that stuff. It's just that this beta has been especially long and I also did the watch 4 beta before this. I just bought a Flip4 to try it out and now it has a beta group runimg and I'm not about to join. I've had enough of betas for now, when I'm in them I take them seriously and work the phone and send in feedback reports. I don't do a lot of posting in the beta forum because alot of that is pointless garbage with a few good posts here and there.
