Order Volume Contraction Since Last App Update

I work in the greater Milwaukee area, and have, even during periods that are typically slow, received a steady stream of offers. Ever since the outage and subsequent update that was rolled out, offer volume has completely dried up. Like... no offers for hours at a time during peak windows. I know this isn't some anecdotal outlier, and my metrics, being nearly perfect across the board, has no bearing on this. What exactly changed on the back-end that would explain this sort of drastic change in a matter of days? And no, this has nothing to do with it being "one of the slowest months of the year". My earnings, throughout the month up to the update, were some of the best I've ever had in my 4 years of delivering. Something isn't right.
