Looks like if i edit on mastodon, it updates on Lemmy. Hopefully it shows up correctly now. (Looks fine on jerboah for me now)

I use syncthing all the time. The ignore file is very powerful and you can get it to ignore whatever you want. The ignore file itself isnt synced across copies, but you can #include a file that is

Im also on lemmy, but looks like i cant edit the post from Lemmy 🙄
