On the device I have flashed the nRF91 with the latest firmware from here: ncs/nrf/applications/asset_tracker_v2. I have flashed the nRF52 firmware with the most recent firmware from: ncs/nrf/applications/connectivity_bridge. I have flashed the most recent modem firmware with "mfw_nrf9160_1.3.0.zip".
I have provisioned the SIM card through nRF Cloud and finally...
Looking at the I checked out the serial output from the device and got this:

Where can I go about troubleshooting this error? I've brought the device all around town with areas that defiantly have LTE coverage. One though is, how do I switch between m1/nb-iot? There is certainly LTE coverage in my area, but I'm not on the list for nb-iot. Inside the firmware downloads there are these files... Some are for nb-iot and some are for catm1.

When I'm creating my build, how do I specify catm1 or nb-iot?
Thanks
