Linked accounts: Credit unions and smaller lenders

Does anyone else have consistent issues with their linked finance accounts? My bank accounts have stopped syncing in early November, and my mortgage accounts have not synced properly since I closed on my second rental and took out a new mortgage with the same lender of my first rental mortgage. The mortgages are appearing to be the exact same amount.

I have two rental properties that I manage myself. When I first started, I used Excel files to manage my accounting. Found Stessa and was excited about getting away from Excel. Not sure that Stessa is a viable option anymore. Maybe its because I use a credit union?

I would like to know what others are experiencing. Trying to decide if I should just buy other software and move on, or continue to wait for things to get resolved.
