While I was finalizing a delivery, another delivery was available. However the app froze and I was unable to accept the delivery. Not to mention the app delays sometimes and I lose out on delivery opportunities. Also I signed on for a delivery that required a red card purchase. I was unable to use it because apparently it needed to be loaded. I had previously activated the card. Needless to say I was forced to unassign myself from the delivery. Please fix these problems!
