PlayProtect is disabled by default in AOSP developer beta updates
Back in .407 and in .424 beta updates, play protect certification is disabled by default. So it is not passed by safetynet, I think. Thus any online transactions may not be secure. My google pay is also not working after installing the beta updates. But worked fine in .63 pie.
Speaker sound gets low, after using the phone for a while. After cleaning app datas manually and after going to recovery mode, after performing wipe cache partition again and again only solves the problem.
I want a stable update with the fixes soon.
