In very rare occasions, when the transactions in an account are updated, a transaction may be duplicated.
This problem does not affect the account value.
If this happens, you can solve it by deleting one duplicate:
• Press on the transaction to see the transaction details.
• Press the blue button with 3 dots.
• Press the "Duplicated transaction" button and give confirmation to the message shown.
Only one of the two duplicates has this button.
