Thank you for the tip! I assume this was for android phones? I have ios and found a similar setting where you reset advertising identifier which basically gives you a new random ad id. Yesterday I got the usual 20 packs and tries to reset the advertising identifier, nothing happened, I didn't get any new commercials. But today I got 30! which I've never got before. So thank you for the tip, it kinda worked
Reseted the ad id again today and we'll see if i'll get 30packs tomorrow too.
