bug!?

is something wrong with contracts? some bug? I mean... I cannot open the tabs (wall of something) only nightmare..

1 wall is empty for me, others load some tasks. are you trying from PC or Android/iOS?

same here

I don't have any problems with my "Contracts" Tab ... weird ...

same for me

Yes, Pc and Android

I dont know but many people expirienced bugs thatt they dont get their gems by doing the contracts idk why i had the same bug too :/

I don't think this is a bug, i think it is a recent change by Gamehag, removing certain advertising or filtering advertisers on your location.
This mostly because some advertisers just never pay to some people (mostly because your location)

Example:
I live in Indonesia
One 'Wall of- ' ' was from advertiser Fyber
I did a few contracts from Fyber, NONE of them gave me my earned rewards
I battled with Fyber support, in the end they gave me the finger on each and every case
I reported my issues with them to GameHag (just like many others like me i assume)
Soon after i reported this to GameHag, all the Fyber offers (1 'Wall of- ' ) disappeared from GameHag
Later i heard some users still doing Fyber contracts on GameHag, but non of them from Indonesia

I think GameHag got tired of being flooded with support questions while there is nothing they can do about this
Actually this is a good thing, you do not need a 'Wall of False Promises' that just waste your time and never pay

I just gave up

i got over 4000 sgs from fyber offer. Too bad if they removed it
