After refreshing the page scrolls to the iframe

Hi, I have a problem that appeared suddenly (everything was working before). After refreshing the page, it automatically scrolls down the page to the iFrame. I would like to eliminate this problem. Do you have any ideas?

Here is my site:

Hey there!
I don’t see anything like that happening. Did you fix it?

No i didnt. The issue still exists. We checked it on 3 different computers, after entering the website and waiting a moment, there is a scroll to the bottom of the page.
