Random factory resets after devices complete GZT configuration.

I am not entirely sure what you mean by Google Play recovery but in my experience with this issue devices with this outdated Play version continued to fail to upgrade Play and would eventually reset themselves automatically in a similar behavior to what we'd see from a ZTE triggered reset. The process would repeat every time the devices in this state with an outdated Play version were enrolled until we manually uninstalled the Play updates on the devices as called out in the article as a workaround. Yet another example where an auto-update from Google has negatively impacted the stability of production devices.
