I think it has something to do with the particular ad and the processing power of your device.

I have no problems with my iPhone SE (newest device).

Some ads cause problems with my iPad Air (several years old).

My iPhone 4S doesn’t cope well with many ads (oldest device).

Sometimes with less powerful devices and more demanding ads I have to wait many many seconds with a black screen, but it does run eventually ... patience is a virtue!

If all else fails, then restart. Resetting the ad id never helped me much.
