So the issue is that the rows are rendered at the top and groups at the bottom when the sortingMode is server

Yes, this is explained in the doc. I keep this issue to track progress on this

This feature is not yet compatible with sortingMode = "server" and filteringMode = "server"

We are also Premium plan customer, do you have ETA on when this may be looked at?

@alexfauquette The doc is saying about it in the Single grouping column section, but it doesn't work for Multiple grouping columns either. There is plenty of time has passed since the initial post; are there any changes or workaround to make it work eventually? p.s. my orderid is 54867, if so.
