Dear Support,
We just discovered the hard way that the LTE link controller of NCS 2.2.0 uses the AT monitor. This is an important change compared to earlier NCS versions.
The consequence is that the application is no longer allowed to use nrf_modem_at_notif_handler_set() because this overrides the call from the AT monitor and prevents the callback of e.g. lte_lc_connect_async() from being called.
While there is a large note in the AT monitor documentation, I think it would make sense to have such information in LTE link controller documentation as well.
Best regards
