Can't connect to the LTE network when upgraded to ROS7.2

Hi All,

We have 4 routers currently displaying this error

Can’t connect to the LTE network when upgraded to ROS7.2

Downgrading to ROS6 fixes the issue - the modem is running the latest version - “MikroTik_CP_2.160.000_v020”

Also tried using /interface lte at-chat lte1 input=“AT+RSTSET” to reset the modem with no luck.
