Before we start, may I know what's the name of the bank? This way, we can check if there are any ongoing issues and give you relevant information about it.
In the meantime, we start a manual download to get the latest available transactions.
Here's how:
Go to Bookkeeping.
Select Transactions, then Banking.
Click on Update.
Once the update is done, this will updated all of your connected banks and credit card account and increase the number of transactions in each account tile.
