I want to open and modify the same vault on two pc, and have the changes updated on the other pc instantly.
Things I have tried
I put a vault in a google drive. vault is opened on two pc, however whenever I modified a note in the vault with computer A, computer B’s vault is not updated, even though google drive is updated right away on computer B. I have to delete the vault on computer B and re-open it. (seems like it triggers a re-index?). Only then computer B will read the updated vault. What gives?
I can always use syncthing on computer B and mirrow in the vault from computer A, but I feel google drive should do the same job.
Are you sure you need to delete it, and reopen? If the local file on Computer B is updated, it might be enough to just reopen that particular file. And possibly you would need to do Settings > Files and links > Rebuild vault cache to trigger Obsidian on Computer B to understand something has happened.
Potentially just a Force reload might update stuff too (or if going through the Command palette : Reload app without saving.
