Later update, NFC

[BiddyBean]

I have just updated to the latest update on my Galaxy z flip 6, now when I scan my diabetes sensor it says that NFC isn't supported on my smart phone. 

This is a very important sensor app, librelink, for me to keep control on my diabetes, but the NFC is turned on. 

Any help please
