I am having this problem, with Interstitial you can create the ad just once and show it multiple times without having to create it again
That does not seem to be the same with Banners... Once you Hide a Banner it seems to be destroyed forever, cannot call it to Show again cause it wont, but Interstitial would!
So I have added "create banner advert" on start of every layout, and show when the level is completed, but since players can restart the layout without completing it, it is requesting too many banners and the match rate on admob has gone from 90% to 24%.... impressions have dropped significantly and the banner wont show anymore even if I close the game and run it from start, admob simply flags it...
Im trying to do this with "large" size banner and it behaves like that, but when using smart-fit size, it seems that I can create the banner just once and use it multiple times just like interstial...
Im kinda lost, just testing over and over app bundles until it is right...
