I just wanted to say that the developers are awesome. I was using iCloud for syncing but started running into issues trying to also use git for backing up. On top of that, iCloud wasn’t always syncing my files (seemed to get stuck on things occasionally).
I switched to Obsidian Sync, and not only do my files sync right away, it automatically ignores hidden folders and files! This allows me to use a git repo on my primary system, and it doesn’t sync that metadata, automatically, without any other setup! Woohoo!
