When I try to upload an SVG that I created in Inkscape into Cricut Design Space, it says "The uploaded SVG contains the following items that are not supported: Pattern Fills: Import anyway?"
I have been using both programs for years, and always do my design work in Inkscape and save as an SVG, never had any problems uploading them into Design Space until the last couple weeks.  I always get the error code above for everything, even though I know for a fact that I don't have a pattern saved.  I don't know if Design Space is the problem or if something changed recently in Inkskape.  I have attached the SVG I'm trying to upload.  Would love any advice or tips!
 

The file looks ok for me - just a few redundant defs wich can easily be wiped off with File_>Clean up Document and 1 double node. No pattern fill detected here.

Can you try this one?

IIRC, DS is fussy and wants only plain svg files with no metadata.

Did you use the File -> Save Template...  with the Set as default template option checked a couple weeks ago?

If so, go to Preferences -> System. Klick the Open button after User templates. Delete the default.svg in that folder.
