How can I link to a Lemmy post in a way that another Lemmy user that can view the linked page without the “You must log in or sign in to vote or comment” message (when they are already logged in)?
And vice versa: how can I click on a Lemmy link and not get that problem?
Yep. Alternative frontend links don’t work. You will have to use the instance’s domain, which is lemmy.ca. You still should be redirected to your alexandrite frontend if you set the Photon UI setting to alex.lemmy.ca in the preferences menu (works for Tesseract, so I guess alexandrite should as well) .
Thanks for the info.
