Hi,
Feel free to share the demonstration link of your experiment with me, here or at support@pcibex.net, so I can take a look
If you say that it was working on the old farm (that is, even using Chrome/Opera/Edge) then maybe what changed is that your project on the new farm uses a newer version of the PennController library. Maybe try downgrading to PennController 1.8 (remember to pause data collection when editing your project): https://github.com/PennController/penncontroller/tree/master/releases/1.8
(download the js file and upload it to the Modules folder of your project)
