"Edit home page" button on front-end store gone

Hi,
After changing to a new computer the “Edit home page” button, usually showing on the bottom of a front-end page, is gone on some of my stores. I can still access and edit all pages through back-end “Customize” theme, but it’s really nice to be able to go directly to the page/product needing an update from front-end. See image under for what I usually see on front-end. Any suggestions what I must do to get this function again?

This button will appear if you are log in admin of that store only

I am an admin and it is visible on all stores on my laptop, just not on my desktop.

Did you login admin of that store on your desktop?

Yes, I am logged in as admin on all stores. But now I found the solution:
I logged out of all stores and logged back in. Then went through all stores clicking on “View your online store” and now the button appears on my desktop as well.
