Could you please retry with microG GmsCore 0.2.23.214816?

@ale5000-git, just tried it with microG GmsCore 0.2.24.214816-23 but got the same result.

Could it be this is related to the actual contents of the QR code, ~I believe it's a BCD code as specified here https://www.europeanpaymentscouncil.eu/sites/default/files/KB/files/EPC069-12%20v2.1%20Quick%20Response%20Code%20-%20Guidelines%20to%20Enable%20the%20Data%20Capture%20for%20the%20Initiation%20of%20a%20SCT.pdf~

Edit I checked some actual QR codes and it's actually a link in the form BEP://1BEP.JFORCE.be:3717/....
