Manage Inventory page - cannot update templates or list items

[cyberspacecomics]

We use the Manage Inventory page to save listing templates and launch items. Since the change in listing format, we constantly get errors when either trying to update a template or save & list. It can take 4 or 5 attempts to finally get it to work. Currently, no templates can be saved at all and no items can be listed from Manage Inventory.

Is this a known bug? Does anyone else have this problem? Help?

I am repeatedly running into this error since last night, I was hoping it would resolve overnight. I am unable to list or update anything from inventory page. 

I reached out to customer service but the chat bot is also having issues giving me an actual option to chat.  I will keep trying.
