Major - P3 Hi
I made an update of my RS from 3.4.1 to 3.6.4,
but application where not using newest driver yet,
so I was enforced to downgrade back
(acc to docu, I have chosen the newest 3.4.14 ).
Downgrade was not possible. Even with data removal (enforce "scratch-replication").
I constantly got error, about config.system.session collection :

***aborting after fassert() failure
I have even tried to drop the collection and db config
but it was recreated.
