Obsidian Sync problems: Linking local to Remote vault

What I’m trying to do

I just made my sync account and I’m trying to connect my local vaults to the remote one now, but the sync option does not show up in my app. Any ideas?

Things I have tried

I searched the instructions for sync, it said i should go into the options on the local vault, into core plugins and then into the sync tab. But this tab only shows up on one of my local vaults and on none of the others? I have the sync plus subscription that allows me to connect 10 vaults, so that shouldn’t be the problem. I’m a little lost here.

nvm the sync tab wasnt activated Im dumb
