I wanted a link at the bottom of a page to go to the next page. I added a row with a text bric in it. I typed the text and changed it to a link. However, now I don’t see to be able to change the text anymore. I in the navigator on the left, there is a lock icon next to the link. If I select the Link, in the properties panel there is a “Label” field with the link text, I can edit the label, but the change is not remembered and there is no difference in the link on the page.
I think you need to be looking at the panel on the other side. You can then either select a page or switch to url and type in a web address manually, which you would use for links to pages on other sites. I’ve uploaded a quick video here:
