I almost wish I could reproduce this myself so I could sniff the traffic. Mine is working great 
I would like to take a peek at some details to see if there are any patterns, might help devs narrow it down.
For people having these issues, can you please let the hub run for at least a few hours (when there is normal household activity). Use this app: [BETA] A Z-Wave Mesh Tool [C7 and 2.2.4+ Only] and get a screenshot of the entire page.
Ideally if you could use ShareX (or equivalent) to get the full thing in one screenshot it would be helpful as well. There is an option called "Scrolling Capture..." which will get the entire page. Recommendation for Screenshot App - ShareX
This chrome extension works also: GoFullPage - Full Page Screen Capture - Chrome Web Store
