Yep, due to the way the some browsers parse the @ sign in urls, we explicitly disabled linkification for any url with an @ in it.

This is change is annoying as many useful URLs no longer work.
Which browsers have broken behavior on parsing "@" in a passed URL and what are they doing with it?

[Brog33]

Hmm. Would like to know as well. Isn’t this an issue that rather needs to be addressed in the affected browsers? And why are these URLs being parsed correctly in the Signal mobile client anyways. Is it only an issue with desktop browsers?

We've done a little bit of research on this - feel free to add a feature request to allow @ signs in link path segments (but still don't linkify if they are in the link's domain).
