For the record, I prefer wefwef being a web app (PWA). It's amazing the flexibility, fast updates, how lightweight it is and being no-store dependent. That being said, I have a lot of freezing in my iOS (iPhone 13, iOS 16) device using Safari as webview. In Android (Realme, Android 12) using Edge as webview I've never had this problem. When it freeze in iOS, I have to swiping up to access the iOS App Switcher, then I tap on it to reopen it, and usually, the app unfreezes after that. Or sometimes I scroll from other screen area and after a 3 seconds it works. Btw, it only happens to me like 1 time every 2 days. Before the updates, it was more constant, so I think it has been improved
