Payment threshold and earnings disappearing

Today I reached the payout threshold in YouTube studio and thought I could enter my bank account in AdSense. I've been earning from 10th of January...

In AdSense everything is still on 0 earnings. Even January...

Am I too impatient?

Then I just checked back in studio and see that the earnings just dropped back by about 1.50$ but the earning from two days ago is still where it was.

What's going on there?

Thanks for your insights 🙏🏼
