Obsidian Sync deleted all of my changes in today's daily note WTF??? HELP

I wrote a lot of notes in my daily note on my PC in Obsidian. Then I opened the daily note on my phone, and everything is gone??? Then I opened the daily note again on my PC and everything in the daily note is gone. That's a whole day's worth of notes since I keep all my notes for work there! Seriously Obsidian?

Is there any open source way for me to keep my Obsidian notes synced with Git? I want to cancel my Obsidian Sync.
