MAX Transit Pro Duo not reading SIM/modem after updating firmware

After updating my EM7411 Sierra modem to the latest modem firmware for Verizon, My Pepwave won’t recognize the connection.
The Dashboard says “No Device Connected” on my Cellular 1 connection. If I move the Verizon sim to Cellular 2 it will show up.
Does the Pepwave only recognize specific FW versions?
