Are you on mobile? I get that error message every time I try to take a Peanut Labs survey on mobile from home. If I try even a mile or 2 from home they work. So you might try taking them away from home. Could be zip code specific. Same with the offers on mobile from home. I get a message saying “ Sorry there are no offers available” but even a few miles from home I get plenty of offers.
If you are on mobile and can access a PC the Peanut Labs surveys work quite well.
I found something interesting today. I tried the offer wall on mobile again with the same result. I then turned of WI-FI and tried again and it worked correctly. Did a one offer for 10 credits and 2 Peanut Labs surveys for 126 credits each. To test I turned WI-FI back on and only the credit reward videos worked.
So if you are having problems with the offer wall and surveys on mobile you might try them with WI-FI turned off. Worked for me.
