Yesterday I started promoting a number of instagram posts, advertising my newly released workout app, Sets (https://sets.app).
A number of times the promotions would not be approved, I believe the reasoning being the images contained checkboxes ; which is unfortunate as that is a core UI component of my application.
This rule was not being applied consistently however, so I managed to promote a number of my posts displaying the main workout view (which contains checkboxes).
Nonetheless, with less than $50 spent I had ~6000 impressions across a few posts! I had a number of sales also!
My app yesterday placed #4 in the Paid Health/Fitness category on the iOS App Store likely as a result of these ads. (I think this is just the Canadian App Store).
