Sorry for the late reply
The problem is happening inside of the Editor, not the Designer.
We try to change a link in the Editor by clicking the link icon, typing in the link and saving the change by clicking on the checkmark.
When visiting the public site, nothing has changed and going back to the Editor shows the old link again.
I have prepared a video for you: https://cl.ly/b28289768d14
In the video I try to change the link to only www.instagram.com, but going to the public site, it shows the old link.
Thanks for your help @Brando, we appreciate it
