Yesterday: loaded some .mp4 videos onto the iXpand, they played as expected (iOS 10).
Today: updated iOS app to the new version 4.3.0, videos not longer play. Restarted app, ejected iXpand, no luck.
The videos are listed as expected, you can open the video, but the video never begins playing. There is no time information for the video, just --:–. Waited, video never starts.
Seems like the app update borked the video playback. For me.
