A team was assigned to work on the offers to weed out the bugged ones and to propose new offers that are better for our players. I'm told they have already made quite a few changes recently and already things are looking better. So, don't give up on them. Your experiences could be better now.
Its far better than it used to be
and tbh its the fault of the survey companies for not reporting correctly on when offers are completed (I assume)
(they dont report completed offers to save themselves money
but iv made a couple hundred AP overall its worth a shot you know
