wilhelmmedetz Thanks! We just submitted an update with a fix to Apple, so that will hopefully be out in the next couple of days. I’ll post back here when it’s released.
Technical details: For offline support there’s two options, Service Worker (the new one) and Application Cache (the old one). As of iOS 15, they did not support Service Worker but they did support Application Cache. Now in iOS 15, they do support Service Worker with some hacks, and removed support for Application Cache. And in the meantime, our Application Cache support (which was special cased only for iOS) was broken by a new feature in our web host (Cloudflare). So now we can finally migrate the iOS app to use Service Worker just like everything else 🙂.
