Build 805 is still in testing (mostly so that store developers, etc. can make changes and test their routines/profiles/plugins) .
if something doesn't work, 1 , use the release thread for any problems,
2, expect it not to work with anything store-related, because it will take perhaps another day to patch anything that the update has broken.
3, you really should include a log to describe your problem, i don't understand what you mean by "don't avoid mode"
