I keep one of my vaults (used daily) in OneDrive and generally have no issues*, although I do get the occasional numbered settings files, e.g. workspace-PC-NAME-2.json

The important thing to remember/set using OneDrive, or any of these cloud services, is to keep the vault or the folder it’s in always local and downloaded to each device you are using Obsidian on. If the service arbitrarily decides to remove files or folders in your vault, Obsidian is going to have a problem.
