I want to sync obsidian vault between devices and i use syncthing for it. But there is a problem with folder permissions. When I create vault folder in Obsidian, Ынтсерштп can read it but cannot write. When I create folder at syncthing, Obsidian can read it but cannot write. Created folder permissions are always read for all and write only for owner (755). I tried to create folder in other app (total commander) and it is the same. I tried to create folder on sd card, with my PC, but at Android permissions became the same - 755.
I use Redmi 9, Android 10
What should I do to use one folder for Obsidian and Syncthing?
