I see all my listing have a red banner and need to have shipping updates. However, when I go into the listing and try to make changes, I get the dreaded " Something has gone wrong. Please try again later"! I need to update some listings in my shop and also can not do this!

I just went back into my Shop Manager; it finally came up. Clicked onto the Listings Page; everything disappeared as it did yesterday. Clicked into my Shop (it's there). Went back to Listings Page, and it finally came up. I think it's making it's way back to the land of the living:)
Today it happen to me when I went to post my new listing and it disappeared.
