Not sure when this started as I listed an item last week without any problems but yesterday I was going to list another item and it seems if you don't select something in the "Enter brand, model" list when inputting the item it won't work. It will either go to an error page with "empty response received" or if you do use one of the items that pops up, and change the title to suite what you're selling it just goes right back to what it was before.
Quite annoying really because in no way am I going to list something with just a "generic" title 😅.
