After completing a transaction with mobile device screen locked, user is returned to "Confirm" as though transaction was not completed

[plasmacorral]

Description

Android 12 Pixel 3a Build 952

If mobile device screen locks before tx gets broadcast, on unlock the user is returned to Confirm instead of wallet/activity view. If user taps "Confirm with Ledger" at this point, an "Invalid Amount" error is presented.

Curiously, if Advanced>Customize Transaction Nonce is enabled after being returned to Confirm, tapping edit presents a nonce value of "ined".

Reproduction steps:

1. Have Ledger paired with configured MMM
2. Have Ledger set to PIN/Screensaver 10 minutes, Blind signing enabled, debug data not displayed, Nonce displayed
3. Have Mobile device screen timeout set to 30 seconds (settings>display)
4. Have MMM set to the default 30 seconds at Settings>Security & Privacy> Auto-lock
5. Have custom nonce enabled in MMM Settings>Advanced
6. Be on a testnet and have assets available to send
7. Tap send from wallet view/ drawer or activity page
8. Select recipient tap next
9. Enter amount and tap next
10. Tap "Confirm with Ledger"
11. Allow mobile screen to be dark between 30-45 seconds
12. Tap "approve and send" on Ledger
13. Unlock mobile device, if brought to login authentication try again because you were a bit too slow.
14. Not that Confirm is presented
15. Tapping "Confirm with Ledger" produces an error "Invalid amount Go to faucet"
16. Tapping edit next to Nonce presents a non-numeric value
