Bank transactions are not syncing. It used to sync all transactions and now most of transactions don't show.
So does this mean your business accounting file has no transactions, or only a few of them, for the past 2 months? Kind of hard to run a business effectively on that basis
If you scan this community and the other L/S community you will find numerous posts with the same problem different banks. All you can do is call intuit support and see if they are working on the issue with your specific bank, and if not get them started.
There is no contractual agreement between the banks and intuit to provide that download service, and any changes the bank makes that affects that connection may break your connection. Several local banks have stated they will no longer support live feeds, since their support people spend way too much time on issues that are not the banks problems.
Relying on banking downloads to make your entries is a misconception intuit advertising promotes, IMO. You should be making the entries as they occur, and then you just match the download if and when you get it, or do a manual reconcile from a statement - 5 min max monthly. Making entries as they occur is the only way to have an accurate current company financial file.
