siteOrigin Builder not allowing widget

I have added the booking plugin Timely: Appointment Scheduling Software on my website
When using my pc it works fine, but when using another pc, a mac, a tablet or a phone it doesn’t work anymore…
I have contacted the the software company who looked into it but they came back to me with the following reasons:
1 - "the editor plugin you are using is preventing the code from running for the widget."
2 - “it looks like the SiteOrigin PageBuilder plugin on your Wordpress site might be the culprit here.”

Does that ring a bell? How can I fix this?
