Benjamin Mayo, 9to5Mac:
Apple began a support Twitter account early in 2016, answering customer queries and tweeting out the occasional iOS tip. It has now expanded into a dedicated Apple Support YouTube channel.
The account features highly-produced tutorial videos explaining all sorts of iOS features from how to change your wallpaper to deleting your call history.
Here’s a link to the Apple Support YouTube channel. Terrific resource, nice find from Benjamin Mayo.
