My first name is Martin but all the messages and awards on the Fitness app (iPhone 12 mini, iOS 16.0) insist on calling me ‘Martyn‘. It’s not exactly critical but it’s annoying.

I’ve checked my contact details and the ‘personal information’ on my Apple ID and they are all correct…
Is this a Siri thing, and if so is there an incantation that can persuade it to spell my name right?
