I have ported my number from O2 to iD, using Iphone 11pro
I am unable to receive texts where two-way authentication is enabled and the organisation sends me a verification code to be able to login (e.g. eBay, PayPal, Tax office).
I have checked all my settings, the correct number is in both phone and message settings.
I tried with iMessage on and off.
I tried rebooting the phone.
Nothing works and I cannot login into my other accounts without the verification codes from the organisations that send them.
