Open a document from an online account
This isn't in every copy of Documents. You need an online storage account, such as Dropbox, Google Drive or OneDrive, added in Accounts.
- Open Documents and tap the cloud button in the toolbar.
- Tap an account, then tap folders until you find the document.
- Tap the document. Documents downloads it and opens it.
When you use Save a Copy on such a document, the copy is also uploaded to the same folder online, as a new file. To go up a folder, use the back gesture.
These steps haven’t been confirmed on LuneOS yet, so some may differ.
