No problem at all, waiting on the expo bus, so have some time! Here’s step by step what I do.
For an 8:00 opening:
7:30 - Get into park; get situated with what ride you want to do first
7:35-7:40ish - Make sure wifi and Bluetooth are off; swipe any and all open programs closed; turn off phone so it has time to do a full shut down refresh [note/edit- you don’t have to keep the phone off a full twenty minutes, that’s just what I tend to do, I’ve had the same results with it off 5-10 minutes]
7:55 - Turn phone back on but don’t click on anything, apps or otherwise
7:57:30 - Open Disney app so it has a moment to do its initial load, but don’t click anything in the app yet
8:00:00 on the dot - Click “Find Out More” (I watch the seconds tick up on my watch with the app open on my phone in the other hand ready to click as close to that instant as possible without being before 8:00:00)
- if “join group” is available on that next screen, click it and select your party, it’s been about 50/50 for me whether it’s been available immediately
- if “join group” is not available, immediately click “Check Status” and “Join Boarding Group” should be available on the next screen
8:01 - Profit!!
Hope this helps!
