You’re probably 100% right. It’s probably just the display of the text that’s delayed for some people. But having seen a lot of crazy
MDE glitches, part of me wonders if some of us aren’t getting into a mode where it’s holding a BG for us, the way FPs are held until you confirm them. I vaguely wonder if going to the My Status screen before clicking Join Boarding Group might work that way. If it works that way for one set of button pushes and not another, that would change the recommended approach.
Probably no way to confirm that though.
