I know the user shops have been updated. But now I can't even create a shop.... When I click the "my shop" tab, I get a blank pae with no options to create one...

It's supposed to redirect you to the page where they can be created, but apparently it's been wonky for some. Try clicking here and see if that does the trick?

Shop Name Type sP in Till Lifetime Items Sold Lifetime sP Made Total Unique Items

Is all I'm getting

There's SUPPOSED to be a 'Create' section below that. Those categories appeared even when I had not yet created a shop, which threw me, but if they're loaded and the creation option is not loading at all, I think perhaps filing a ticket might be the only option.

(I'm trying to show you what it looks like on my screen, but blasted Windows 10 doesn't appear to have the snipping tool I am used to, so...I dunno how. Technology wins again.)

I haven't had a laptop since windows 7, so I know what you mean about new technology. Add that to not being on Subeta for like 4-5 years.... But I'll definitely file a ticket
