Logseq via the browser: keep getting 'file journals...has been modified on the disk"

I’ve been attempting to use Logseq via the browser, as I have a new device at work and no longer have admin privileges to install the desktop app.
Problem is, after every few seconds of typing I get this prompt: “file journals/2023_03_15.md has been modified on the disk.” I then have to compare two versions of text, one “on disk” and the other “In Logseq.”

The fact that it happens every few seconds makes it impractical to use. Any ideas on what’s going on and how I might resolve it?

Thanks very much,
