What a pickle! Have you opened a support case with VMware and maybe Google?
And what's the reason for staying in Legacy? Both Google and VMware have been deprecating features and support for Legacy for quite some time.

We want to have deeper test on Android Enterprise before migration. So want to use Android Legacy instead.
