I logged into my G-Suite Marketplace inside Cloud console to update the add-on to a new version. I had been testing the add-on in Spanish, and upon logging into cloud console, it was in Spanish and had a brand new UI.
OOF.
I updated the version in the configuration tab and upon going to the Store Listing Tab, there were now three buttons at the bottom - where previously there had been just two.
I didn't understand what the buttons meant and (I'm embarrassed to admit how dumb I was), tried to copy button text to then translate back into English. In so doing, I clicked one of the buttons.
Now, my add-on is missing from G-Suite Marketplace (users can't download it), and they no longer see it in their Sheets Add-on menus.
oof.
I still see the add-on inside G-Suite Marketplace in cloud console, but it has said "under review" for two days.
How do I get my Add-on published again? Both the Save and Publish button are greyed out on the Store Listing tab.
