When I tried to join other teams, if the "Bubble Gum Event" had not been completed, players could participate, but if the "Bubble Gum Event" had been completed, they could not join. The point is that it has a limit on the number of times, and it seems that you can only participate 3 times, and then you have to wait untilβ¦
Last night, I also got this event. I was very lucky and got 60 minutes of unlimited lives, which allowed me to keep checking the levels required for the community competition.
