WvW Panel: For our squad, it turns out the trick was to open the panel AFTER scores reset. Those who were ready early and opened the panel before the scores reset had large lock icons on the options and had to close and reopen the panel to get into a BL that way (and by then... queues). So it would have been nice with this "tip" from anet about using the wvw panel to be a bit more specific about when to open them.
I had the WvW panel error and got stuck in a queue. The reason I opened right on the hour (just before scores reset) was because in the past if I opened the WvW panel after the scores reset often the menu wouldn't work - the options would just be greyed out. So in my attempt to bypass the bug I knew about, I ended up getting stuck in a queue because of a new unknown bug.
On a positive note:
1) On reset night our squad didn't have the large disconnects that have been happening lately - several people simultaneously disconnecting. On some nights it has been 3 or 4 times with as many as 6 people disconnected at once, which really ruins the fun when there are large queues.
2) Queues for this beta are better than in the past. Not sure if that is because anet balanced teams more effectively or if less people are WvWing right now, but it is more hopeful to see there are less than 10 in line ahead of you than 40+
