It opens https://www.youtube.com/oops for me, and with the crash reporter: « The playlist doesn't exist »

You forgot sharing the last _ with NewPipe, so this is not an issue.

[opusforlife2]

What? 😆 No.

I copied this link from _within_ Newpipe, and shared it with _another_ Newpipe. GitHub ignoring the underscore is probably a markdown artifact.

This most certainly is an issue. Considering your comment, @wb9688, Newpipe (not the android clipboard, since it works from the search bar) is ignoring the trailing underscore.

[wb9688]

Sharing from NewPipe to NewPipe indeed doesn't work. Sharing from NewPipe to browser to NewPipe does work though.

Not for me. I'm sharing it to the release apk. Which apk are you trying it with?

@wb9688 @opusforlife2
The reason for it crashing is that the RouterActivity removes the last underscore from the shared url here.

This happens if you share it as an url from the browser (1) and do not use the "Open in App" action (2). Reason being that (1) goes the "if" path where the above mentioned method does NOT get called and (2) goes the "else if" path where it does get called

[opusforlife2]

So am I understanding it correctly that the underscore is mistakenly identified as a regular expression that needs to be removed?

That's how i understood it from going through it with a debugger.
But i have no clue what the intended use case for that regex is.
