How many people have been getting the following message when using fivebacks at CVS:

Alternate Form of Payment Required

I and several other area MSers were have been unable to use fivebacks at CVS the past 1-2 days. I tried every combination of credit/debt, swipe up/down, buying 1 card or 4 cards, etc. Nothing worked. Trying to figure out if this is the beginning of the end for this method, temporary system error, bad batches of cards, being done on CVS's end, Blackhawk's end. Any DPs appreciated.
