I am having the EXACT same issue with my PayPal Bank Feed.  Until about 6 weeks ago, the bank feed transactions would automatically match to a customer's payment.  I only had to verify a handful of them for accuracy before accepting the matches.  Now, NONE of them are matching.  I have to Find Match for every last one of them (hundreds).  It is such a waste of my time to have to do this.  On a positive note, I'm glad to see that I'm in good company and not the only one with this problem.
