Wrong QR code address when paying

Scanning a QR code to pay someone, without G1nkgo mobile app installed, open the Cesium app instead and display an error message.

Is it because the QR code address (june://my-address:XXX?amount=Y) is not recognized by Cesium ?

Or maybe it should be without the checksum at the end ? Maybe it's just a Cesium error (Cesium 1.7.3).
