Steps to reproduce

1. Create a new folder
2. Upload / copy / move a mp4 file to this folder.
3. Change file name by giving a special chracter like '+' or '&' or whatever.
4. Create a shared link for this folder. With or without password doesn't matter. Do not create a shared link for the mp4 file directly because this works.
5. Open the shared link in a new browser tab.
6. Try to play the mp4 file inside your browser. Do not download the mp4 file because this works.

Expected behaviour

A window should open and playing video / mp4 file.

Actual behaviour

A window opens and shows a message: "Fehler beim Laden von [file name]" (Maybe: "Error while loading [file name]")

This error message only occurs if you call up video / mp4 file inside a folder which is shared by a link!

I have the same problem.

More info about this issue. If I open the console and looking at network activity, I see that the request and a name of the file in that is not url encoded:
http://localhost/s/12345678/download?path=/&files=test file & with special symbol.mp4=
Therefore special symbol, & in this case, breaks the link and give 404 error, instead of file.
If I url encode file name by hand:
http://localhost/s/12345678/download?path=%2F&files=test%20file%20%26%20with%20special%20symbol.mp4
This link is works.

I think this was fixed in NC21.0.2
