I experienced the issue on a 6S+ but not sure if I took a screenshot, I'll look when I get back home next week. Don't think it was limited to an add though as I turned on airplane mode as a last ditch effort to stop it. Instead it seemed to load a placeholder that consisted of a single centered white pixel and a red tab offset to the left that still blocked the inventory and weapon buttons even though they weren't actually covered by a graphic. It usually occurred within the first five minutes and exiting would only temporarily fix it.
However I did just download it on my 6S and adds seem to be working as intended so far, but I'll use it a bit and see what happens.
