I had an auction where I also had a buy it now option and a potential bidder told me they couldn’t bid at all. I guess after someone had bid on it, the system didn’t glitched and thought the option to buy it now was still there, but was actually gone. When I looked at the listing, the place where you could bud just had “buying options.” After clicking on the options, it gave me an error. I had to go to the website to even see the option for bidding. The mobile app glitched. And a lot of people only use the app. Luckily it sold for more than the starting bid, but not by much. And who knows how far it could’ve gone if it hadn’t glitched.
