Two problems with OneDrive on iOS 11 when working with Files (well maybe 3 problems)... 1) On an iPad Pro, in Files, when selecting OneDrive, it pops up a new window for OneDrive. It's not integrated in like literally every other cloud storage provider. 2) In Files (on iPhone and iPad Pro), when browsing OneDrive files, it shows some, but not all of my files. For example, I have one folder that has 17 folders in it. In Files, it shows maybe 3. In the OneDrive app itself (outside of Files), it shows the correct data. 3) The email client now uses Files exclusively for attachments and you can't use your cloud providers directly. So as you can imagine, browsing my files shows the incomplete listing from #2 above, not the full list. If I want to email a file located in my OneDrive, I have to open up the OneDrive app, select the file, click Share, then send file, then pick my email client. Argh! Is Microsoft even aware that these problems exist?
