I use it as test wallet, I find the design really cool.
No issues so far for me.
Remember that without KYC, ZBD has a withdrawal limit. I don't know if you reach it.
Which games specifically are you having this issue with? I seem to recall Sarutobi giving me some issues back in the day but I'm not sure. To be honest I just play these mobile games occasionally to burn some time and it's nice to be able to support Bitcoiners when doing so, I never cared much about the rewards. Hope you can get this sorted if the sats are important to you though.
I was more worrying about the concept of play to earn in general tho. It's not going to stick if people don't have a seemless experience with it!
And I want EVERYTHING in the internet to become small financial transactions via Lightning to give incentives to the right things one day.... Like Stacker News!
