I meant start with a new account with a new email for a new trip and just abandon the existing account after any trips on it are done. It's not ideal, but it might be the only way to make things better in the future. Sorry it's been such a hassle. I already have two accounts with different emails, but I hardly ever use the second account.
This was in July, but both my husband and I have iPhone 7 on AT&T. We got BG at 10am for 3 days without any problems. One of us would use wifi and the other cell. One of us would always get one for the 3 of us. I think it's really random and not everyone is going to get one. I don't think any of these special things people are doing really matter. Just be on a join page logged in and ready to go. If it's just one person trying, I would probably use cell.
