Hi,
We want to programmatically enable or disable this group feature on our scheduler. By default it should be disabled. Once user choose to enable it then we need to show the resources as under groups.
This line we are using to disable the feature.
scheduler.features.group.disabled = true;
To enable the feature we are using
scheduler.features.group.disabled = false;
But after this feature is disabled, it's never enabled again.
I am able to reproduce the problem in your examples as well.
