No Caller ID on incoming calls - help!

[J43]

New iPhone 14 pro 2 days ago. 24 hours ago I ported my old number across. Since then all incoming calls have said 'no caller ID' even if they're in my contacts. Outgoing calls work fine. Anyone managed to fix this?

I'll tag one of our account advisors @O2MichaelE who is on this afternoon.

Hopefully, he will be able to help.

Thanks Cleoriff. Just spoken to O2 Customer service who've told me it could take 3-7 days to resolve, so any advice would be gratefully received. Seems to be an issue lots of people are experiencing.
