I have noticed that while trying to use any plugins that add a HTML Header, they do not work at all. I have tried removing all APP and PAGE wide HTML Headers to see if they were conflicting and that is not the case.
Seems like something that would be a given for a plugin and a development platform - That HTML headers across the board would work. Hopefully its fixed as I am paying for multiple plugins that add HTML headers to the app and they aren’t working.
