sharing to nextcloud: inconsistencies

Expected behaviour

Select in third-party app, sharing, choose nextcloud

• hootsuite: ok
• twitter, safari, firefox focus/firefox, linkedin, netnewswire: not offering nextcloud

I suppose that sharing target is based on source content but like a commercial notes tools, you should be allowed to share to target and eventually choose format, like text only, text+media, full html...

Also sharing is always to one or multiple files.
Can't share to Notes which sometimes make more sense

Last if try to edit filename during sharing, save button becomes greyed out and have to cancel.
or make a file operation or attempt, like sliding on left, like if you want to erase and save become available again

Actual behaviour

see above

Steps to reproduce

Take third party app and try to share content to nextcloud

Reasoning or why should it be changed/implemented?

Inability to use application while it likely should.

iOS version

13.3.1

App version

2.25.9

Server configuration

irrelevant

Start by reproducing the third-party share flow on iOS 13.3.1 with the listed apps and Nextcloud app version 2.25.9. The issue covers missing share targets, format choices, Notes sharing, and a disabled save button; done would require an agreed scope and verified behavior for the selected cases.
