I usually use CAMT.053 for import. It works fine.
I now wanted to import CAMT.052 (transactions for the day up to this moment). Manager accepts the file but reports no transactions in it. I know for a fact that the file does contain 3 transactions. If the next day I download the CAMT.053 for the previous day, it shows the same 3 transactions and imports them correctly.
Is importing CAMT.052 a program feature? If not, I think the program should say so and not accept the file and silently drop the transactions from it. If it is, there seems to be a bug here.
