iOS Base Currency Adjustment
On iOS you can’t adjust the base currency so it’s difficult/impossible to Publish foreign transactions as you need to make sure they correctly matched to the bank statement. Can you add an additional line with the case currency so you can change it similar to the way you can on the web version? It would make the need to login online less necessary.

Currently in the iOS app, you only see the foreign amount from the receipt, when abroad, but often your Bank send a notification showing you the amount that was taken from your account in your local currency. As a result, you would be able to update the receipt to the correct home amount so that it matches correctly.
