I ended up just subscribing to Obsidian Sync. Not saying everyone needs to go do that, but it works really well, and I love being able to sync my notes abroad without having to VPN back to my home server. The convenience is nice, and I got tired of fighting Syncthing (I still use it to sync my pictures and music to and from my server)
I figure even after buying the $25 Support license, I use this app so much and it is such an important part of my life, that it was worth supporting this small company pumping out such a fantastic piece of software. It feels good to do my part to financially encourage them to keep going and I benefit from it too
