Yes, AFAIK the app does use an external VM database that must sync up the Hub and App. As for the Pods, I'm not sure. I did read on here recently about using the WPS function of the Hub to re-pair the Pods. That may be worth a try ?
As for the app itself, I never use it. I tried it once as a test, but as it didn't pick up the Hub, nor the VM wifi, it was uninstalled. 99.99% of the time I use modem mode, so it was of little use to me anyway.
