App Volumes v4 Failing to Mount

I am using RDS 2016 VMs that are instant clones. If I restart the instant clone VMs, they attach the app volumes VMDK and I can app stream the application that is packaged as an app volume. However, if I recompose from the master image snapshot, the VMDK does not mount on the VMs initially (I have assigned the app volume to an OU that has the domain joined RDS instant clones). This was working a week ago, and I'm not sure what caused this to start failing.

Below is a log snippet from the app volumes log. I've also attached the full log.

Did you ever figure this out?  I'm having a similar issue.  V4 Apps will not mount while v2.x appstacks will

I never found a solution. The workaround for me is to manually reboot the instant clones after their first boot up, and then it mounts the app volumes correctly.

AppVolumes 4.1 has just been released.

Check the release notes, maybe a fix.
