Welcome to the forum, and Apologies right from the get go… No to insult you, but sometimes it is the little things that trip people up, so please bear with me as I try and give you some things to try.
Some obvious, some less so.
Phone on and screen unlocked?
NFC turned on? ( Apologies I haven’t checked your phone specs )
Phone cover removed? ( Can prevent good reads )
Do you have diagnostic card or xField Detector to find optimal position of antenna?
Check this Wiki for some pointers
Can you try and read with this app?
I hope you weren’t too insulted, sometimes people come on here and miss some things in their fault finding.
Good luck
Let me know how you get on
