Bright suns, everyone. I just wanted to share my experiences from the last three days at DL.
First, don't get discouraged. I have been able to get BG12, BG7, and BG10 the last three days. It's my opinion that if you read the thread, and follow the techniques described, you WILL get a BG.
The key is timing. Having a clock with seconds display on your phone is crucial. And use the network time. Don't use any kind of atomic clock program that is synced to NIST. That is not necessarily the same time. Mobile networks use GPS time so that everyone's on the network is on the same time.
Anyway...practice switching from the clock app to the DL app at open. Have your DL app open to the "Find out more" page. Time your switch so that you are on the app at open. It's not that difficult. If you've done it right it will be red when you get there.
As I've said, I'm 3 for 3 with this technique.
I'm on a pixel 2XL on VZW.
Best of luck to all.
(Forgive any typos or rambling thoughts. I'm typing this from Docking Bay 7 waiting for boarding to start)
