Clearly not for everybody. I'm Andriod (Samsung) and still showing Norwich. Same for wifey. Looking at the FAQ's, it says the process is automatic. It might be staggered release, and appear shortly, or it might be because Samsung is slightly different on Android phones and the automatic process isn't working.
Although the option 'add to mobile wallet' is greyed out on the Arsenal ticket on my City account, it is available on the seasoncard itself. I'm leaving for a couple of days to see if anything happens and if it doesn't, I'll download the seasoncard again.
