Hi @EugeneErg. I get a “Something went wrong” error on the first link and a 404 on the second link. Maybe you could share some screenshots?

These are truncated links showing exactly what changes when creating a frame in the Notion.

@EugeneErg Quick question: Have you set start view? 

You find it under Settings->Board->Set start view in the top left nav.

When clicking Set start view, you can choose any area on your board to be your start view:

I have several frames. And I don't need controls and scrolling. You are trying to solve the wrong problem that I asked. If I take the page code and change the link in the frame, then everything will work as I need. But Notion won't save my changes. The problem is that Notion is replacing my link with another one that doesn't work the way I want.
