Reinstalling Google Play Services seems to work, either. Procedure is: disable “Remotely locate this device”, move back to manufacturer version and then upgrade, and enable “Remotely locate this device”.
Google Play Service 11.3.02 (436-161239932)

Angry Birds 2 – 2.15.1 (526084620309)

1. Since Saturday everything works perfect. Thanks for you assistance and support, Hank. Have a nice day.

Me neither, crashing almost every time. Only mentioned previously ads are played. I’ve restarted OS and nothing.

Fruits Mania from Ad Colony OK. Next ad frozen like hell :)

[choochen]

Next ad is not starting at all and game’s frozen again. There’s no hint what ad and from whom.

[choochen]

Updated to 2.15.1  ad displayed, FoE from Unity Ads

[choochen]

Did you see what ad it was before crashing?

Unfortunately not, but sometimes it’s successful. I will update next time when ad will be successfully played.

What country are you in?
