Think there may be a little confusion as to what a 'beta' and what 'beta testing' is.
It is literally for people to test what is given, report bugs and issues, said issues are fixed and re-tested in the subsequent incremental releases. A beta is not for the implementation/addition of new, revised or improved processes. That all happens in the architecture and development phases, way before any users in the real world get their hands on the 'beta'.
That's not to say that Samsung have not caused these confusions themselves right, leaving people far less than happy.
Greater explanation is certainly needed from all the posts on here. I have seen so many around Google Pay alone even though it's a well known fact that it has never worked under Samsung Beta releases, well known, well known to people who have participated in previous betas, so this was clearly not communicated to people new to the circus or at the very least not communicated well enough. Just using GPay as an example. This is also a Google 'security' measure AFAIK to prevent it being used under custom Roms, firmware. However I think I read somewhere that this may be fixed with certain tweets by Samsung in the future.
On the final 12 release, delete cache and data on GPay, uninstall, restart device and reinstall GPay.
Samsung certainly need to redraw the line between beta and suggestions.
@GoanGeek explains it perfectly but not everyone knows this based on so many posts out there.
This is all a real shame as it leaves people unhappy which is not what the whole process is about
😔.
