Good day, samjeffs.
Thanks for the additional information and the screenshot. I'm here to give you more details about banking.
It would make sense if you'll get an error when changing the source (payment) account of the transaction because they are downloaded from your bank. Therefore, changing the payment account will contradict the reality they are from your bank account.
If you really want to do this, you'll need to open the added transaction, change the payment account, and unmatch it from the online banking transaction. This step will remove it from the original account and will transfer it to the payment account you'll select.
Simply open the transaction then change the payment account. Once done, click Online banking matches and tap Unmatch.
Additionally, you don't need to unlink the bank if you just want to change the payment account. It'll show as deleted after you undo the added transactions and unlinked the bank. It's because all pending transactions will be removed once you unlink the bank including those transactions you undo.
Also, you can manually add those transactions to the other account. This is also the best way so we can avoid confusion and errors.
Please comment again if you have more questions. Stay safe and healthy!
