I had a nice, first upgrade experience. My setup is a mesh with the main A3 wired, a secondary A3 wired and a third A3 wireless. I chose to update the firmware from the iOS app. After a few minutes, my internet went out for about 90 seconds and was back up. I checked each A3 and verified that they were all updated and they were. From the iOS app, I clicked on each A3 for status and the wireless A3 showed that it was not connected. From the status screen on the wireless A3, it showed that it was connected to the mesh and had all the info about the devices that were connected. So, I restarted the wireless A3 and that fixed the problem within the app and everything is running smoothly. I am digging my A3s! Thanks!
