If you have your own instance, that is true. Otherwise, on a good instance, I’d assume the host has already taken care of linking all the communities. Especiall, because otherwise the posts won’t be aggregated.

I’m guessing that the reply you’re referring to, is from a person that has their account on lemmy.ca, and because of this, you were provided the link to their home instance. Of course this sort of thing is unintuitive, because now you’re on a different website that looks the same, but suddenly you’re not logged in anymore. People who don’t read too much into the details of Lemmy are now just confused why they are seemingly logged out and can’t log in anymore. On the other hand, you also want to reply to that comment still, so you’d have to manually find the comment in your home instance instead (or type the URL with your instances prefix).

Lemmy is still in its early stages, I’m sure there’ll be a lot of quality of life fixes soon, pretty sure they are flooded with bug reports and feature requests right now.

I guess it’s good to keep in mind, but are people having issues with drift on their sticks? I’ve been using my deck quite intensively and so far had no issues.
