Google Play working subscription .aix with video

I am seeing way to much people not showcasing their .aix billing extensions. I also see that for those that have purchased the extension are saying its not working as it should. So I am asking for proof in the form of at least one person who has purchased the extension with a video showing the .aix import then the blocks then it actually working on a phone app. I would like to also see someone who has purchased the .aix or .aia extension to give their view on the extension. Also, the more you showcase the more you will sell.
