The only thing that allowed the bank rules to work when the information is missing from the Bank Feeds is to ignore the Bank Feed items, download a CSV from the bank, and then import it into QBO.  The banking detail that we are accustomed to seeing was in the CSV information for Chase.  It was a little extra work but far less than opening the checking account or statement and looking up each individual transaction to manually process.  My Chase bank feeds did eventually start working again.  I had the client do an update with their owner login credentials and it seemed to start working shortly after.
