Fairphone 3 with LineageOSMicroG does not allow to login to DigiD (Dutch site) with QR in DigiD-app.
This LineageOSMicroG is based on Android 13.
Have tried in Firefox and Chromium.
The use of QR codes in e.g. my bank app, works fine.
Using my old FP2, with LineageOS based on Android 11, and APS, it is possible to login to DigiD with the QR code…
When filing an issue, I see there are specific settings in MicroG that I completely missed, and that may be well related to the issue: Installation · microg/GmsCore Wiki · GitHub
I have the same issue. Other apps, including banking apps can scan QR codes without problem. But DigiD can´t. The camera turns on and I can see the QR code, but it never ‘clicks’.
I have LineageOSMicroG with Android 12.
