I seem to be able to get CTD at almost any 3rd party airport on my series x. In fact I get them at Asobo airports too (just CTD at Asobo LFMN in A320 on short final). And I get them at other times too, even on beta .21. It’s better than SU9 for sure but still a long way to go to be acceptably stable.
Performance is generally very good with SU10, much better than 9.
