Hi,

it does work only if you share a folder with a document in there, but not the document itself.

Wow. I'll test this later, thank you for the clue.

But why this behavior isn't mentioned anywhere? Still, sharing a folder is not the same as a document with different permissions for each.

[Orchal]

I don't think it's intended, it's more likely a workaround, so I guess your issue is still relevant!

Hi, after update OfficeOnline from 1.1.2 to 2.1.0 and update to 28.0.3 we have a problem with open shared documents. Nextcloud won't open document for reading or editing if allowed. Only option is to download a file. But if shared forlder with a document, all working.

This is a important task. Users want to be able to view and edit content directly from a shared link.
