If someone try to use the Proton Wallet app to pay for something there is a good chance that the will encounter the "not a valid bitcoin address", as many payment processors using the BIP21 and Proton Wallet will not recognize the BTC address from within the QR.
This issue came up when a costumer of mine wanted to pay with BTC from the Proton Wallet app. Of course the BTC address can be obtained from the qr code via a QR code scanner app and copied into the wallet app, but then the BTC amount also needs to be inserted manually. Errors can be made during these to steps which makes it more risky.
Logically the same thing will come up when a unified QR code is used (which also gives a lightning address within the same QR).
It would be nice that the wallet can read these QR codes as well, so it will be easier to use to pay via these QR codes.
