New version is AC3 NOT compatible :(

Think before update, the new version is NOT ac3 compatible

Why is AC3 support not given in 2.4.1?

I think it's better to not update the program if the new version es worse than the older. No one tell why but they confirm that now VLC is not Ac3 compatible.

AC3 support is no long in the new versions of VLC for IOS. The last version it worked in was 2.3.0 . Dolby Digital has demanded Licencing of the AC3 format, so VLC is not allowed to keep it in their app without paying licensing fees.

Hopefully you have a copy of the old version on your iTunes computer that you can restore. Remember to check in the trash can for the older VLC 2.3.0 IPA file, and if you successfully restore it, remember to disable automatic app updates on your device if you have them enabled.
Settings > iTunes & App Store > (un-check automatic downloads of updates)

If you don't have a old copy, unfortunately you are S-O-L!
