Very long ads doesnt share between devices

The game is good. I paid extra for the difficult game and the game is good. They now changed to ads to 30 seconds and I cant use the difficult version on my other devices without paying again. I tried contacting them twice and they answered after a few weeks. I think its wrong to make longer ads, pay again for other units. They contacted me and said if I would purchase apps in the ads that come up the ads would be less than 30 seconds for a while. If you look at anything even in the same app the ads start over. Shame on them for being so greedy.
