there was such a problem when viewing ads. I have two connections to the Internet in the same city (different operators) - both with static IP addresses. I also use LTE mobile Internet from time to time.
if I watch ads on IP1 and the mobile Internet - everything is OK, everything looks great
If I watch an advertisement on IP2, then the maximum that I can squeeze out is 15-17 green rests. at the same time today, in order to get 15 rests, we had to look at about 40-50 ads.one more option - you look at one advertisement - you get a rest - then to see the next one you need to exit the game and re-enter

help solve this problem. I know about clearing the cache and advertising ID — I do it every day before viewing (no matter what connection I watch for advertisements).
