I have watched a bunch of the videos on the mobile app...only to not have them credited to my account. the first few give the payout as promised, but then the credits stop being added. the videos continue to play, so I am basically wasting time watching advertisements!
there is certainly no problem with putting a cap on the earnings amount, but please go back to the "sorry, no offers available" pop-up at that point.
the 80-100 credits I am missing would also be greatly appreciated if they showed up on my account :-)
