No one is even mentioning the fact you can not upload files to a web site since DB2, I think this is one of the most basic things to have working in a beta, let alone a public beta. I made a similar post elsewhere to the point that I believe most people are only concerned about specific apps they run and control center. I mean come on, seriously, there is a lot more to iOS than most people even fathom.
I also totally agree with anothe poster that iOS is going backward to an old file folder seek n find utility and is very un iOS like and apps need to have the ability to be told where to look for files if not readily available as recents showing in the files app, we are still stuck searching for a file based on where it was last saved and in which cloud service.
Apple needs to make file access magical and effortless. The spotlight is the closest feature related to this issue and even that they are now pushing to the background. Hopefully they have a few aces up their sleeves and by GM everything becomes apparent why the Files app is currently behaving like an old Windows 3.1 system but will be utilized into a way better optimized system by release time.
