Hey Stuart,
Iām new to this thread so would you mind posting the video again so I could see how youāre posting the URL?
Iāve reviewed your posts and based on one of them:
it looks like youāre using the Inline Editing feature because that is currently a known bug with that feature that Iāve personally replicated and which will be fixed in one of the succeeding releases. In case you donāt know yet, Inline Editing is activated when you double click on the text. Youāll see an interface like the screenshot below.

Are you inserting links like in this screenshot?

If that is the case, then itās currently a bug. Please use the full HTML or Rich Text editor for now.

You can tell your editors to switch to Rich Text for easy link inserting.

If that is also the case, weāre very sorry for all the confusion.
For the Button element, Iām wondering how you insert a link to a button. You can activate Inline Editing to edit the text but it does not have a link option.

Would mind showing us how you work with buttons also?
Thanks.
