Hm weird, I have no problem with alby here... Pop OS 22 - same as ubuntu 22, using the deb install. I'll zap you to demonstrate.

It may be you have some extension that interferes with it. probably nos2x maybe itself, no idea really.
tbh I'm not keen on anything involving keeping secrets on browsers, but unfortunately the bulk of UI devs work with browsers and the support for GUI on my preferred language is abysmal.
Zapped you back, ironically via Alby, kind of - I wanted an out from phoenix for sending so tried to use Alby on brave - the connect button never caused anything to happen, total block, so I downloaded Zeus, connected that to my alby acc and use that for zapping now, and nos2x on kiwi for web based nostr on mobile, because I didn't fancy keeping my nsec on Alby
