I think this has been reported last year, that 3yo’s could only have 2yo schedules because Training Schedule page was thinking that they’re still 2yo. I wanted to change a schedule for one of those, Andzia, she’s a 4yo now. I got the message “The schedule you selected will not work with this horse because it is 2 years old!”.
I’m guessing my horses may be bored having the same schedule for two years now, so I have two schedules that are suitable for 2yos and I will use those…
