The post parade has been moved to the new app. 
Nothing new here, should be the same setup as the old app. (Note: I haven’t done a mobile-specific view of this page yet, but it’s on my to-do list.)
Claiming has also moved over, and has some slight tweaks.
For horses that you can claim (e.g. you don’t own them, and you haven’t put in a claim on any other horse), you will see the Claim Horse button next to them
If you own the horse, you will see a non-clickable button saying so. (Just in case you forgot 
)
If you already have a claim on another horse that race day, the Claim button will be disabled on all the other horses.
However, now you have the option to delete your claim in case a new horse pops up that you’d rather put a claim in (or you just change your mind on claiming that horse).
Give a shout if there are any questions / issues.
