Sage advice. Thanks for your help and, hopefully, this will be the end.
By the way – how will newer owners know when to upgrade their firmware? I don’t recall seeing anything special on the page although it’s possible I missed it. When I click on the link for the firmware files, it the link sends me the ZingOrbit_V170711.zip file without taking me to any other page. Maybe a new page could be added with the various firmwares and release notes about each one? Maybe some warning for future users? Just a thought and friendly suggestion to pass on.
