New markdown was created or modified, but it was not updated immediately. click online to refresh and update
If I click to change the markdown in the outline, it will change the markdown of the body. But If I change the markdown in the body, it will not be reflected in the outline. It will be updated only when I click outline to refresh it also
As you can see in the picture, "follow cursor" was checked body-outline instant synchronization worked fine until about 3 weeks ago, but it's suddenly stopped working since recently
Please help me if you know the solution.
