Unable to upgrade app

I’m unable to purchase the prime membership to unlock level 5. Every time I press “Buy” option I get “product purchase failed” error. Also, unable to view “IQ abacus Tempe” in near by school in the maps, due to this unable to find anyone to do the battles.

Developer Response ,

Hi, we have fixed the bug for purchasing the membership. Please try again and let us know if you still encounter problems. Sorry for the inconvenience.

Worthless app. Doesn’t do anything.

I thought I can download the app to do some math practice. All I was able to do was... well... nothing. Things can’t even be clicked. I’m starting to think those 5 star reviews are probably fake. Deleted the app after 10 mins trying to figure out what’s going on. Tried my best to figure out but it’s literally worthless...

Hi, it's been a while since you tried the very preliminary version. We've been updated the app for several times and tested a lot since then. We know many students are excited about playing and battling each other. Hopefully you are willing to give it a try again and let us know how it works this time. If the map of you MM Go does not show any landmark, please turn off the "location access" from the settings and play. Thanks for the feedback.
