Modem manager unable to attach correctly to a 5G SA network but 5G NSA is working fine

Hi. I am testing with a Quectel RM500Q modem on different flavors of 5G SA/NSA and it seem that modemmanager is unable to correctly attach/connect to a 5G SA network but has no issues with connecting to 5G NSA. (Have been able to connect to 5G SA using libqmi by itself but the convenience of modemmanager is nice)

What kind of information would be needed for needed in order to further the debugging of this. I can provide ModemManager --debug or whatever is needed from the device side and maybe also traces of the attachment procedure on the network side if necessary.

Regards.
