Hello I am wondering a question about double xp factor
1 - after applying double xp token does the timer show I don’t see a timer
2 - does the double xp token apply to 1 hour of actual time or just in game time

1) timer does not show. So you'll want to write it down somewhere to keep track until the implement it.

2) real time, whether you play or not.
So if you use your 1 hour and lose power immediately and come back after an hour. It is lost.

start the xp tokens as soon as you see the count down when the lobby appears. Use your phone's clock timer to keep track.
