What I’m trying to do
Trying to downgrade from the insider build to current public version but version still shows up as latest insider version
Things I have tried
Turn off insider build, turn off auto-update , delete obsidian and install older version but still show up as 1.2.3 not 1.1.16
I guess you have to cut out (later: delete) the path of obsidian somewhere downwards %AppData% and install the older release (automatically at the same place). (Unfortunately I’m on mobile phone at the moment and have no access to Windows to give you the path). Analogue on Mac, I guess.
