I'm not sure about it, that's the reasons why I asked.
I have that version on my website because, That's the final license I bought from themehouse, so I have to renew my license, and check lots of add-on compatibilities before I run upgrade. I don't wanna break the live website, and my localhost has the upgraded version. I have no way to test it before upgrade. but fb.watch links are not working in my site. so I thought it would be a good idea to ask this from the developer before I upgrade your add-on.
