Articulate Storyline Moodle iPhone Video Playback Issue

Hi,

Since the latest iOS update to 17.6.1 my modules no longer work smoothly in Moodle on iPhone.  Modules that include videos now crash halfway through the video or the video lags and stutters badly. Most video files are a few minutes long and are around 30MB, so nothing crazy.

Not just new modules either, it seems to have affected all modules that have been published for my app, some of which are over a year old and were working without issue until this update.

There seems to be no issue in a web browser and I've also tested in SCORM cloud without issue. It just seems to be limited to my SCORM packages in my Moodle app and only to iPhone (we've tested on iPad too and they work fine on there).

I also got numerous people/clients with iPhones to test, all with the same issue.

I just wondered if there were any new known issues with this iOS update that anyone was aware of? Or if anyone else is experiencing anything similar?

Thanks,
Andrew
