New 3.0 Update Not Showing!

I read an article that says VLC has added Chromecast support as of version 3.0. Id love that feature but unfortunately Im on version 2.9 & there is no option in s app store for me to upgrade the app (•̪̀●́).

Please tell me I can get the update w/o having to update my iOS first...

iPhone X, iOS 11.1.2

*If you fix that & add stretch (Not crop) to fill screen I will give this app 5 Stars.

$up3r annoyed!!! about VLC for Mobile, v2.9.0
