The app is great. But if the developer is reading through review. I believe there's more to contribute for the proper usage of this app. If my phone got missing, there should be a way of accessing my account without waiting to import and export. It happened to someone recently. Her phone was stolen and when she got another phone, there is no way to access this app unless she imports which is impossible. I believe more update can be done regarding that. Thank you

Google Authenticator v7.1 fails on my Samsung Galaxy A36 (Android 16, One UI 8.5). Tapping "Transfer accounts > Scan QR code" immediately shows "Something went wrong" and the camera never opens. Camera permission is granted, Google Lens and Samsung Camera scan QR codes normally, and reinstalling the app didn't help. This appears to be an app compatibility bug. PS.: The bug has been fixed.
