"Unhandled UR message" when registering a multisig config from Sparrow via QR

[tokyovyse]

When attempting to register a multisig configuration (as per https://help.blockstream.com/blockstream-jade/add-more-security-functionality/back-up-a-multisig-configuration-on-jade), the Jade Plus shows the error "Unhandled UR message" when scanning the descriptor QR code.
This is not a user-helpful error message.
This occurs whether scanning the entire QR code or the "Less Dense" animated version, or also the exported PDF. This is with the latest DEB version of Sparrow 2.5.4.
Jade firmware is 1.0.41.
If I've missed something then just let me know, but it appears to be a bug either in Jade or in Sparrow.

@tokyovyse which QR are you trying to scan for the registration? you will need to pick the Jade Multisig option

Hi @bitcoinhelp, thanks for the reply.

Indeed, if I go through the "Export" option rather than scanning the QR code of the descriptor, then it does seem to work.

When scanning a descriptor and getting the "Unhandled UR message", it would be useful for that error to be more descriptive, since the QR of the descriptor seems to me the most obvious one that a user would choose.

However, I confirm the functionality does work when selecting that Export option. Thank you for the pointer!
