I have downloaded v1.2.1 build# 355--the latest recommended by the update notification in ABP and it breaks the Google Play Store. By that I mean, it won't allow (or, isn't being allowed) connections to the Play Store. The Play Store returns the message
Server error
[Retry]
The worst part of this is my Nexus 9 can't update ANY of the installed apps because of the block.
I've reverted back to build 343 and that seems to work sporadically...
