Since the app has reportedly had many glitches, and is now having a glitch that is impacting you, now may be the time for you to avoid this actual problem (and any future potential problems) by heading back to the computer.

There is nothing that anyone on these boards can do to fix the app's technical problems. You're not contacting eBay by posting on these boards. They are public forums on which any eBay member can post, and the responders are, like you, fellow eBay members who give voluntary helpful advice and information. eBay's IT department don't read here, and I've never known an eBay glitch to be fixed as a result of eBay members posting anywhere on these boards.

Contacting eBay's Live Chat is unlikely to result in anything other than script-guided consoling words and a promise that the issue will be escalated to the IT team. This will be a meaningless response designed simply to soothe the person making the complaint or asking that something be done.

I'm sorry; truly, the best that I can do (and that anyone here can do) is suggest that sellers reacquaint themselves with eBay on their computer.
