In Safari on iOS mobile devices, I noticed:
1) Users must click two different play buttons to play video.

2) There is a noticeable half-second pause after each edited clip in the video giving the appearance of jerky playback.

3) When changing mobile browser settings to request desktop website version, the original unedited video plays instead.

These issues were reported over 7 months ago and continue to make hosted videos unusable for iOS users.
