"We're sorry, some data in this report is delayed, please try again later. There's no impact to ad serving or payments." Last few days I saw this message on my account 3 times. less than 24 hrs 2 times, do you think it could be the reason of ctr drop ?
There is no reason (unless legally) for Google to post the red bar some stats delayed message. Their data in the 2 years is already delayed. So essentially what their red bar message means is data is delayed even more than usual. How is that helpful to publishers?
I know that on a Monday, in mid-November, by 3pm, I should have accrued $200+ in earnings. If it's only $150 and I see the red bar, I can rest easy knowing things will catch up. If there's no red bar, that means something else is wrong and I have to start investigating. *
