This app in conjunction with Marketplace is horrendous. Responding to inquiries about my seller listings is costing me not only money and time, but a sub par impression to those inquiring. I respond to buyers, but the response takes days, even sometimes never to go through at all. This leaves a communication deficit and both parties in limbo, leaving me with a back log of idle responses. Being unable to sell items after a loss, and trying to prepare to move has been a tad overwhelming..
