Yeah, screenshot on Monday, messed with the app that evening, tried using it Tuesday morning -- dead.

I've seen people on PureGym's Twitter successfully refreshing screenshots weekly though, and the API response suggests the same.

That being said, I couldn't find a validation endpoint to check if mine got invalidated by something specific (maybe signing out?) or if there's some other magic happening.

I wonder if opening the app invalidated it, and those people who had it working just screenshot once.

My gym has a similar system but I realised it's time based and the app functions without Internet. I installed the app onto an old android with no sim, logged in at home over WiFi and it successfully regenerated QRs without data
