@btcpleb please upgrade to beta3 KeyOS v1.4.0-beta3 is now available for testing , this will unlock your transaction. Go to Wallet, tap the three dots on the top right corner, Settings, and make sure the Verify Full Input History is toggled off.
Verifying the full input history is only important for offline signing devices working with segwit, as attackers could fake addresses/amounts to be displayed on offline devices. In beta1 we enforced the full input history verification by deault for security reasons, without realizing some wallets like sparrow don’t send this history. In beta3 we left it to the user to make the compatibility vs security tradeoff decision themselves. Note that you can have it on, and if you scan a vulnerable PSBT you will be given the option to one-time waive this security filter for the PSBT you scanned. Also know that Taproot addresses are not affected by it and are immune to this type of attack.
Thank you for the ptience and for the report!
