Unable to edit a note or create a new note in the Nextcloud app while offline

Steps to reproduce

1. Put device in airplane mode
2. Open Nextcloud app and attempt to edit a note
3. The editing tools don’t appear when offline
4. The Nextcloud app doesn’t display the option to “Create text document”

Expected behaviour

The editing tools appear when working offline. The note can be edited and the changes are uploaded when the server is available again. The Nextcloud app displays the option to “Create text document” when working offline.

Actual behaviour

When working offline editing tools aren’t available and option is missing to “Create text document”

Reasoning or why should it be changed/implemented?

Since users cannot be connected to the Nextcloud server at all times, it is necessary to edit or create a text document when offline.

Environment data

iOS version: iOS 14.6

Nextcloud iOS app version: 4.0.4

Server operating system: Ubuntu Server 20.04.2

Web server: Apache

Database: mariadb

PHP version: 7.4.3

Nextcloud version: 21.0.1

Reproduce the airplane-mode steps in the issue, then locate the iOS app entry points for offline note editing and text-document creation; no file or test is named. Done means editing tools and document creation are available offline, with changes uploaded when the server is available again.
