It doesn’t seem to be a Signal-specific problem. Signal uses a link detector embedded in UIKit/Swift or something:
NSTextCheckingResult.CheckingType.link.rawValue: https://github.com/signalapp/Signal-iOS/blob/2d6fee16cd92cedf20eafaa3908df0be32d4e9b3/Signal/src/util/DisplayableText.swift#L129

(If this is wrong, please correct me)

Hi @gabrc52,

Is there a valid URL with two #s that does not linktify? The one provided is just an example domain.

[TheBlckbird]

This URL is valid, but it's uncommon.

[gabrc52]

Yes, links to Matrix rooms have this format: https://matrix.to/#/#matrix:matrix.org
