ZBD works over my VPN (for now) but third-party apps like Sarutobi don’t.
Hmm that's not a ZBD created game though. It's a third party dev using the ZBD API I believe. Maybe ask the developer about that specific issue?
I won’t because I already know what their answer will be.
I'll email the dev.
Sure, here’s what you can say: My friend is trying to earn sats for playing Sarutobi, but your partnership with ZBD is preventing him from doing this. He lives in a region that ZBD doesn’t serve, so he has to trick their server into letting him login by using a VPN to mask his location to connect his gamer tag. Your app won’t let him use a VPN to collect sats. Please allow him sidestep ZBD’s compliance rules, because he’s just a humble freedom-loving pleb. Thank you.
