is only an idea, but we have lot of case where manual removal of cloud data was helpfull ( there are also other topics about in forum with slighly different steps - is just not so easy for MS cloud, compared with e.g. Steam ).
Sometime I also wonder whether more users which switch from PC <-> Xbox run into these kind of trouble.
PS: but yes… these removal should be a bit easier for gamers ( or better not necessary )
