Bug Description

Users are getting stuck on the last page of the Notabene flow, the one with the "Your data is being verified", while showing a loading animation (see screenshot).

So far it only seems to be happening in the Android wallet, and some users had more luck with the Android version of the CryptoX wallet. The CryptoX wallet is a third party wallet based on our reference implementation, but it is based on an earlier version of our app. Maybe something has changed in our app since? It could also just be luck of the draw, we can't know for sure.

But I have Concordium mobile wallet installed. I have other crypto wallets like Trust Wallet, TronLink Pro, Blockchain Wallet, Binance Wallet and Atomic Wallet installed on my phone.

For completeness, I want to add @td202 slack comments here as well:

"I think it's likely to be caused by the app failing to parse the redirect URL. This is because in some of the failing cases, users are presented with the option to choose which application to open the URL in, which means the page is trying to do the redirect. It's just the app isn't processing it correctly.

This is the code that does the parsing, which looks like it could be a bit sketchy, though I don't see an immediate problem: link

Unless #code_uri= can occur more than once in the returned URL"

We haven't experienced the issue ourselves and therefore have to await users' reports, if it is not solved.
