Have an domain with a fileserver.
External users working on iPads need access, to upload pictures and edit excel docs.
Thouhgt of using DattoDrive (like dropbox), to seet up sync. works great on pc's and android phones, for booth needs.
But on iPads, they can upload pictures, but when opening excel docs, it only previews, and don't open in excel.
Tried using Onedrive for Business, which works for doc's but no upload of pictures..
It needs to be simple, take pic and click upload, choose forlder - save.
Open excel doc, edit and click save.
