But of course the only way to get a test in Ancestry's database is to test with Ancestry, as they won't accept transfers in from anywhere else. I took a test with LivingDNA in frustration at my repeated Ancestry failures, and of course I was able to upload that to GedMatch and other sites, which did find a few 3rd to 5th cousins that I was able to identify, but I still wanted the Ancestry test. Having eventually succeeded, I have had far more useful matches through Ancestry than all the other sites combined, although of course I have also obtained some useful matches from the other sites, who weren't on Ancestry.
