Hello @ebourlet & @Legionetz,
The models support with the new NTP Server features can be found here:
The Pepwave MAX BR1 Mk2 does not support the new NTP server features as it does not contain an RTC (real-time chipset) with the battery as mentioned here:
There is no bug with the firmware in your model as the NTP Server component does not exist within.
Happy to Help,
Marcus
