It's been stable here and I like the new design of the start menu. Usually Release Preview doesn't have any major bugs as its the slowest branch.Is there some indication that they've addressed the issue in the release preview? (I'm still registered for insider, but have no real desire to be a guinea pig.
But there might not be any fixes to 2004/20H1 at this point as they'll just push everyone over to 20H2.
