robin can you check unity ads on iOS? i have them enabled for rewarded video ads and they are showing ok and the blocks are working fine but once i have finished watching a video and i close it none of my touch events work anymore... and i have to close my game and restart it. I have seen several videos (adcolony, heyzap, chartboost) and this is only happening to me when a unity video is displayed. oh and on android all is working fine, this is just on iOS.
i'm testing on an ipad mini 2, ios version 9.1
