By "abandon ship" I mean to cancel the upload entirely so it can be started over later. There's no Cancel button on the page. I was referring to the Package Builder which does have a Clear All button. Since it was a dependency issue, I wanted to delete the var, then upload what looked like the same var, though the content was different. The page did not regenerate the var health check, or any health check when I re-uploaded the var. When I gave up fighting with it, I submitted the new var, and the report was correct. It just never showed me the health check before I submitted it. I used F5 to reload, but not Ctrl-F5. I'm on Firefox 121.0 with up to date Java.
