The login/logout issues between the two platforms are our top priority to fix. I know they're causing a lot of frustration (for me, too) and I'm sorry for my lack of communication with you all about what's going on behind the scenes on these issues!
We've had developers working on this since last week, and it's apparently much more complicated than those of us without much technical background could possibly imagine. As of last night one of the developers working on this has reported some progress, but we don't yet know if the issue is completely fixed or not. Personally, I'm not having the same problems I was having previously with being logged out of Discourse when I navigate there from the home page.
Are you all seeing any improvement, or still having the same issues?
