I was impacted by the bank feed/BMO disconnect this week; my connection now appears normal, but no transactions are being imported. Anyone else experiencing this?

Try opening your QBO account on any private/incognito browser.

Makes no difference. I also cleared the cache as was suggested.

It still says "All caught up" on all of my accounts, yet I know there are new transactions I have input which appear in my accounts when I log into BMO. It should show them and allow me to match them as it usually does.

You can use MT Online or one of the converter tools (e,g csv2qbo @ $60 one time license) as a workaround.

Why should I have to buy a tool as a workaround?

This has been working for a year now. It is nothing new. It was working a week ago.

I had received notification from QB that the BMO connection issue was resolved. They made no mention that transactions would be affected.

I am having the same issues.
