Good to hear that OCdude.
I keep getting constant prompts (iPad Air 2/iPhone 6 (non s) that say "install ios11.0.0 or later then visit the AppStore to download the latest versions of' numbers/pages/keynote/word/excell, third party apps, 4th party, everything - more or less.
However, you've got to watch for the apps you use a lot but dont support 64 bit, and there are some on my iPad that dont (KORG MUSIC apps for example). And there's no certainty that the developers will migrate to 64 bit so, for now, ill leave things alone and say on 10.3.3
