Honestly people who give ata shish about the offerwall need to relax, it’s not their control at all in any way the ONLY part they have in it is the agreement with fyber to let fyber run the offerwall on pimd.
That being said...
Fyber isn’t always the best when it comes to support or giving the “okay” when an offer is completed. When you download an app or agree to do any kinda survey or trial etc. be aware you might not be rewarded SO if you’re willing to possibly waste your own time then attempt an offer. Otherwise expect the possibility that it won’t end in your favor. The offers do pay out (I’ve gained 2k ec in the last few days) when you send support messages but it’s always a 50/50 chance with any offerwall on any app
