Is there anybody who know how to handle this issue ?
nobody from unity would know unless you submit bug report.
tested with chartboost, admob, iAd, unity ads
well, chartboost/admbo are third-party plugin, so if you can create small repro with unity iAd impl or unity ads - drop case number so we can have a look
Yes, Even in my game I started noticing same with unity ads…It precache ads in background but I think since it is video ads so game & internet connection takes load. So the game running in foreground starts lagging. Any solution for this?
I suggest replying to Alexey’s post above with the case number he asked for. That does seem to improve the chances of a response. You got a comment from a Unity person, make the most of it.
