iOS macOS Server account for Numbers not available after iOS 12 update
I have a Mac mini running High Sierra and hosting a server network based on the macOS Server app 5.6. I have various iOS devices that as of iOS 11.4 had 'OS X Server' accounts and using e.g. Numbers could maintain files on the server. I emphasize 'maintain' - read, update, save; read, update, save; etc. I have used this Numbers capability for years.
I recently updated my iOS devices to iOS 12.0.x and now find that I can no longer access my server based files. Also the is no longer an option to create an 'OS X Server' account using the 'Passwords & Accounts' option in iOS Settings.
My question is, under this new iOS 12 environment how do I locate the files that I been maintaining since mid-September 2018 using my iPad Pro that are currently 'lost to me'.
I realize that my server is 'functionally stabilized' at High Sierra / macOS Server 5.6 as macOS Server 5.7 guts the server app but has 'Mojave' as a pre-requisite. Needless to this that update is not going to happen.
I find it somewhat obscene that Apple would continue to sell a macOS Server app for the same price as the version that functionally more rich. Obviously the unwarded 'Open Source' providers have pushed back; or Apple have decided they no longer wish to take responsibility for maintaining their offerings.
P.S. I think the Apple Support categorization is ****!
