Unity ads Crashe on mobile

Hi, We have just built our unity game with the unity ad sdk. everything worked fine until it tried bufferinf the ad.

The device crashed whe buffering for video ads and it quits the app

has anybody else had this problem? and if so what are your suggestions.


It can happen when you have more than one scene in the game

I have only one scene in my game, but i am also suffering from that same issue.
I have also facing the same buffering unity ad issue on my iphone and iPad both.
When ad gone in buffering , then i must have to restart the game. I can’t do anything.
can anyone have idea, how to solve this issue?
Thank you in advance.
