Edit in Makerworld doesn't work?

I am editing one of my models but after uploading new STL files I am stuck.

I cannot get to the next step because the “publish” button is greyed out. What am I doing wrong? Or does Makerworld have an issue?

I think I figured it out. I use Brave as internet browser and how I set it up doesn’t work with Makerworld stl upload function anymore (used to work fine). If I upload the stl in Chrome it works fine.

On Brave just disable Shield for MakerWorld.com

Yes that worked. Thanks!
