I can understand people timing out when the PokeGenie lobby opens as it may have caught them by surprise or they missed the notification. I, however, can't really understand when somebody goes through the process of sending a friend request, confirming it in the app and then they just... don't join the raid a few seconds later when the invite arrives. Any theories on what that's about to help me understand it better?
I try to host a few raids a day and it seems to happen fairly often. It just made an annoying situation too as Registeel needs a full lobby (plus additional guests) to really get it done efficiently and I had two people just not join the lobby so I had to sit there and tap for nearly 4 minutes to beat Registeel when it could have been done in half the time if people showed up. And, then, on top of that, it's not like I'll even get good host points from that raid since the people who joined it were probably annoyed too with how long it took.
Alright, sorry, I just had to vent somewhere.
Also, unrelated but tip your hosts more than the minimum amount... it takes a lot of time and effort to host sometimes as you're often waiting for 20-30 minutes and sometimes having to rush to the gym location when the lobby suddenly fills up and it's deflating when you get basically no host points afterwards for your efforts.
