In my project 2 layouts. On event sheet 1 layout set "Preload banner" and "Preload full screen ad". On 2 layout set "Show banner ad then user press Pause or game over. Every 3 game over set "Show full screen ad" , every 45 seconds set "Refresh banner ad". But its work correctly only if i wait ~10 seconds on 1 layout and when Jump on 2 layout. If i imminently turn on 2 layout both banner newer show! I think, this is due with slow download, but why download canceling?
