From Bank feeds the list of matching transactions from the match existing transactions option has most of the transactions to match missing. This is both transitions to match ones that existed before the problem and ones added later. 

The problem showed up about a week ago after a QB update that required a company file conversation.  The same thing happens if I restore a backup that worked before the update.  QB converts 

the only transaction that showed up is one from September 2023 with show last 30 days or show all.  All the other transactions are missing.  No nothing shows up for last 30 days and a half dozen show up with view all.

I think this happened just after an update and after the update the existing company file was converted to a new format.

To be clear bank feeds is working; the banking transactions show up.  It is the locally created transactions like invoices and customer payments that do not show up.
