Hi All, I'm new to the Fediverse but I'm slowly learning about it and it excites me. It has shown me that there is more than the big services to be enjoyed.

However, one thing I'm not sure on is how to following users across the Fediverse works. I have an Lemmy account on lemmy.world instance and I have a Mastodon account on mastodonapp.uk instance.

I have installed the official Mastodon app, I searched and found my Lemmy user account (@SonyJunkie@lemmy.world) in the app and followed it but when I post on Lemmy these do not show up in the Mastodon app or timeline. I tried @ing my Lemmy account from my Mastodon account and it obviously showed showed up in my timeline but I didn't get any notification on my Lemmy account.

Am I misunderstanding how this works? If so, please can someone explain it to me using words of one syllable or less!!
