I’m trying to update one of my existing asset packs. However, when it comes to the part where I select the supported engine versions, I cannot check any of the checkboxes (see image).
Please ignore this. I was thinking this was a kind of version control mechanism. I see now it is more of a product definition. I was able to successfully update my existing product by NOT adding a new version, but instead updating the existing product definition with a new version number and new upload URL.
