Verify Key confusion

[ildella]

Steps to reproduce

1. I had very old sessions on both Ubuntu and Android apps. None was verified, but I Was logged-in in both, and I could see my spacs, rooms etc..
2. On Ubuntu app I go to settings, security, Reset secure backup. A new key is created, a classic backup key made up of 12 4-chars strings. I store it.
3. Now the Ubuntu app is still not verified, the Secure Backup says This session is backing up your keys. and Cross-signing says Cross-signing is not set up

Now, if I try to verify the session, I'm asked for the key.

If I upload the key from the file, no error is reported, but "Continue" button is disabled
If I paste the key, a red error appears "Wrong Security Key".

So now I am stuck. The support over Twitter told me to upload logs so here I am.

Outcome

What did you expect?

Not sure to be honest.
I expect the Ubuntu app to be automatically verified after the Reset, and then to verify android and web apps using the new Key from ubuntu app

What happened instead?
