Thanks to @terceanI was able to test the follow instance feature with a #Pixelfed instance.You can also test it by following pixelfed.de
You will be able to Fav, Boost or comment on Pixelfed posts with your Mastodon or Pleroma accounts :)
Why is this step necessary? mastodon.social might not be the server where you are registered, so we need to redirect you to your home server first.
