HELP! CTR Dropped like a stone all of a sudden.

Hey all.

as of today my adsense on Youtube Click through rate (CTR) has dropped like a stone off a cliff. It was around 9% - 12% for months every day and today its 2%!!! What happened? Anyone elese have this issue today?

Is it google not working properly? Ive checked my videos and ads are running fine also my view count is normal.

Same thing happened to me
My views have dropped 80% since the update

my ctr is about the same but the CPC has gone to shit
