We have had this same issue since April 2020 as well. But we are on Quickbooks Desktop Premier 2019. I have not been able to sync our Chase accounts to QB since April 2020. I just a week and half ago tried adding one of our newer chase accounts to the bank feed but no transactions were synced at all. Since this appears to be a problem on both QB Desktop and QB Online, the issue is definitely not the browser being used. I think it’s something between you Intuit and Chase that needs to be looked at. Maybe Chase updated something on there end without telling you all or vice versa and that has caused this issue...
I have absolutely no problems syncing our Wells Fargo accounts so it’s something with Chase.
