Hi @vmsysadmin201110141,
What kind of issues are you experiencing? Do you believe you're missing profile settings for applications that are configured/profiled? Are you using the UEM Application Profiler --> http://pubs.vmware.com/uem-91/topic/com.vmware.ICbase/PDF/user-environment-manager91-app-profiler.pdf ?
You can also have a look at some existing profile templates created by VMware and the community --> VMware User Environment Manager .
Just curious to hear what the exact issues are and if there's anything I can help you with.
I use App Volumes and UEM successfully at various customers. The whole idea of using UEM is to have flexibility and speed for your users by managing the profile (settings). I do agree that it takes time to profile all the necessary application/environment settings, but see it as an investment that results in happy users having speedy logons/logoffs.
I am not sure about the question regarding writable volumes and if it is supported.
