Nothing that has affected my environment. Zigbee and Z-Wave devices have never been an issue for me.
Something that you may want to look into is what channel Zigbee is running on, on your hub and what channel your WiFi 2.4ghz channel is on. If they are sitting on top of each other, that could be a potential cause of issues for you. Not every problem is the same out here. Could be interference, not a strong enough mesh built in your environment, low battery causing disruption, faulty device, etc…
In addition, the whole Device Health being turned on can cause some screwy results as well so you may want to turn that off and reboot your hub.
