Hi, I have a Numbers spreadsheet on my iCloud Drive. I want to share it so it can be edited and updated by other people. When I select to share via iCloud I can send a link via email. However when somebody clicks the link on an iOS device (iPhone or iPad) a screen comes up that they can download a copy of the spreadsheet to Numbers on their device or they can live update it on the web if they use a Mac or PC. Importantly if they download it then their updates are not uploaded to the original. Now please tell me I am doing something wrong. If you can't collaborate on a document on an iOS device then iCloud Drive is the biggest pile of do do since humans left caves. Google Drive works exactly as you would expect, allowing use of the iOS app to update shared sheets. If you know another way to share (such as through Dropbox) then please do tell. Thanks.
