adds did not working on new videos

on my recent videos add breaks did not working, adds appearing only after 3-4 days when video did not have views anymore, before that i can see only one add break in the beginning of video, all my videos are longer than 10 minutes and this problem started about 1 week ago, because of that my revenue dropped dramatically, anyone have this problem and can someone tell me what i can do to resolve this problem?

monetization icon is fully green and my channel did not have any strikes or problems
