Symptoms:
Inconsistent Maximizer firmware versions are reported.
Troubleshooting Steps:
Tier #3: Verify the actual firmware status using pex-spy-client to ensure that firmware is genuinely out of date.
Confirm that the not-updated Maximizer(s) are connected to the mesh and are transmitting data.
Re-update the firmware.
After the update, meticulously confirm that the updated Maximizer has not been inadvertently 'lost' from the system.
