I've been using it for a couple of years with Google Drive on Windows, on a near-daily basis, with approximately 300GB across multiple vaults - some very large files, some very small text files (think Obsidian).
I have not encountered any errors / issues / lost data. I do frequently get a message where it tells me it can't lock the vault because it's still "in use", but I just Force Lock and go on with my day.
Exactly - exactly my problem. And why I'm probably going to reluctantly upgrade to the $25/mo unlimited. It just irks me that I feel like I'm getting ripped off :P
Imagine installing and opening a separate units conversions app just to find something that used to be an instant search away.
