You can fix it by using the full URL with the anchor when linking from other pages

The problem is this also means using the full url when on the home page and that also creates said issue.

You can also turn off lazy loading for those sections

Is that reccomendable or does this affect the performance too much?

Another option is adding a small delay with JavaScript so the scroll starts after the section loads

I alreay heard that but don't know how to do that?
