Why no more ads?

Watching ads used to be my go to to a few extra lives to finish a level. I no longer have that option and it is killing me. I am making no progress and can’t win any challenges to get extra resources. I have drained all my resources of gold bars and other helps. I can’t keep paying money to buy more resources just to pass another level. I’m stuck on level 4939 and am about to be done with this game for good. Help!
