Favicon and Link Images

[parabelflug]

Why do I have my favicon with the test page, but NOT with the LIVE version? Why is there still a mistake in this canonical? Why is the image of the LIVE version so matschig? The screenshot is from the links as they look in Notion

I would appreciate, if someone has an explanation for me and how I can solve that.

Solved!
It was the cached version, which I saw. Explanation link by Google: [Suchoperator „cache:“ | Google Search Central  |  Dokumentation  |  Google for Developers](https://Google Cache)
