Telit FN990: All supported/current modes not reported (MM 1.20.2)

Mon Nov 28 11:19:15 UTC 2022

Attaching full log and relevant portion seems below. No it's not regression. I just loaded 1.20.2 mainly for 5g support.

Hey,

Could you please run MM with debug logs to see what the modem is replying?

Also, just to confirm, this is not a regression, right?
