I also have x50 chipset phone and have some problems with it.
Sometimes it logs only NR messages and not LTE messages.
Sometimes it logs only LTE messages and not NR.
It is also limited in UL power as it is not able to share power dynamically between NR and LTE.
This is a major issue as it limits the VoLTE coverage in uplink when NR is activated.
This is why MNO policy is to disable NR if a VoLTE is initiated.
Especially due to x50 chipsets.
All those 5 G smartphones will pretty much reach recycle bin within 1-2 years from now.
