Good news. I am glad both VMs are up and running.
I am not RecoverPoint expert, so cannot say if RecoverPoint has enabled CBT.
Have you deployed these VMs from template? Maybe it is enabled on the template VM.
My colleagues confirm that SRM does work with multi-writer flag (using array based replication).
Regarding the statement in the KB, it only relates to vSphere Replication that cannot be used with shared VMDKs.
I will try to get the KB fixed.
