QuickBooks Online (QBO) depends on the data shared by your financial institution. Here are the possible factors why you're having no bank feeds for two weeks:
The bank is performing system maintenance.
There are notifications from their website that need your attention.
First, let's manually update your bank account to help resolve this.
Go to Banking from the left menu.
Select the blue tile for your bank account.
Click Update.
If the update doesn't work, I recommend logging into their website to check if there are messages that need your attention. When everything looks good, perform another manual update.
Once downloaded, I'd suggest categorising your bank transactions in the For Review tab to ensure they're correct. If there are existing entries, click Match to avoid duplicates.
Lastly, can I ask for the specific bank you're trying to download transactions in QBO? Also, did you receive any error message? Just click the Reply button below to add some details to make sure I've got you covered.
I'll be around to help if you need further assistance. Keep safe always.
