Expected behavior

Ultimately, the XRP is transferred to another wallet. An intermediate step is, that the tx is signed and correct QR code is shown for broadcasting.

Desktop (please complete the following information):

• OS and version: iOS
• Version [e.g. 22]

Additional context

BTW, the release 1.1.0 on Github for Ubuntu contains an outdated recovery tool (v1.0.0), while the Mac package is the expected (v1.1.0). But this is a minor.
