Nothing broken or nonfunctional or anything. I’ve just been more of a fan of Cinnamon (and Xfce before that). I hadn’t tried Plasma in any real capacity in years, so figured I’d see where it’s at now; it’s fine. So they’re more complaints than issues - “old man yells at cloud”-type stuff because I have to figure out everything again, which is frustrating when you have a workflow.
I’ve made edits and deletes, and as far as I can tell, once the instances sync up, those edits/deletes are synced as well - I have noticed a delay, but it usually kicks in like overnight (for example) when I make a change using my account on lemm.ee for my account on lemmy.world to see it, etc.
