Yes, but that’s even hard on youtube, because you have to scroll down.
The mobile version of this is kind of clunky, but PeerTube seems to mirror the functionality with the desktop version of YouTube.
It’s easy to do though, despite quite hidden. If you aren’t logged in and press comment or subscribe peertube asks you for you fediverse handle and redirects you to your fediverse instance (on mastodon: corresponding post for comment; follow popup with the group/user for subscribe).
Why can’t that be exposed on the main login page? The general public are used to OAuth logins, where you can pick to use a Facebook, Google, Apple, GitHub account to use, instead of creating a new one. Just expose that kind of UI to the main login pages, everywhere.
A common UI trap is to only have one way to do something and use that as justification that the feature was implemented.
It certainly doesn’t work with lemmy right now.
Which is a shame, but there are few bug reports in GitHub about it at least.
I had a similar experience. I like the idea of PeerTube, but not the execution. It needs significant improvements to make it more friendly for viewers to use as a video portal, rather than relying on subscribers and platforms like Mastodon to fill that gap.
