The MAX BR1 Mini (LTE-US-T and LTE-US-T-M) with active Verizon SIM card will experience the cellular connection issue after upgrading to firmware 8.1.1GA (8.1.1 build 5009), eg. detecting the Verizon SIM as ATT/TMobile, or, no APN selected.
We have prepared the fix with the new GA firmware (8.1.1s033 build 5014) and it has been updated on the firmware download website. Please load this latest GA firmware to the affected unit(s).
Other MAX BR1 Mini variants are NOT affected.
