Hi @sygnoossupport, sorry for replying today.
It is weird, but my boss entered with a different user to the WP-Admin Panel, and she did not have the problem that I had, we don’t know why, but she was able to set up the pop-up properly.
I guess the mistery of why it wasn’t working and how to fix it will remain, but at least it works now!
Thank you for your time and patience, take care!
Regards
