If you have an account at one instance, you can see everything from all of the instances that are federated with that instance. If there is another instance that is not federated with the 1st instance, then you have to make an account there to see anything there
I’ve experienced that several times, especially since, on desktop, I like to middle-click and open any link in a new tab. Then I have to copy that URL and paste it into the signed-in instance to subscribe or upvote

But currently there is no redirect to preferred instance type of settings available which in quite uncomfortable to me.
For example, I created an account on lemmy.world instance and click an url like https://lemmy.world/c/asklemmy@lemmy.ml, it redirects to lemmy.ml instead of lemmy.world instance.
