Okay yeah on Android itself it’s not working. I was checking in the browser on my laptop in mobile mode.
I’m not sure how I can debug this though. My guess is it’s a conflict with another JS script that fails on mobile. Possibly an ad or analytics script?
Can you login and check the preview area on MetaSlider? Does that work?
Can you disable other plugins for a few moments to see if it fixes anything?
