iOS Barcode Scanner (QR) not working

Hello,

I'm using Powerapps to scan a QR code which contains plain Text to fill out a form. On Android everything works as it should but on iOS the Barcode scanner opens the camera scans the code and immediately closes afterwards and no value changes...

I'm using the normal BarcodeScanner control set to Auto. At first I was using UpdateContext() to fill out a form which is triggered OnScan this worked on Android but did not on iOS. Then I tried using ClearCollection() to gather the text from the QR code, again it worked on Android but not on iOS...

I also tried the Barcode reader (preview) and the Web barcode scanner both of which I couldn't get to work neither on Android or on iOS.

Is it a known bug that the QR code scanner doesn't work on iOS or am I doing something wrong?

I have not had any issues with the standard barcode scanner on both iOS and Android, but the one in preview does not work at all currently for us either.

So let's say we have a QR code containing "test" as plain text. If you scan that with an iOS device you'll receive the string "test" when calling BarcodeScanner1.Value ?

Exactly, we have production apps using that control and it works great.

Is it an old phone or an old iOS version?

Interesting, we tried it on the newest beta version of iOS and on the normal released version. The weird thing to me is that the QR code scan works flawlessly on Android and the exact same scan wont work on iOS...

I'm building a new version of the app now maybe that will fix it. I'll update any improvements here.
