When you download PK Rewards on your phone, it should automatically install on your Apple Watch if it's on and next to your phone.
However, sometimes the app downloads onto the phone without downloading properly on the watch.
To check this, open the Watch app on your phone.
First, scroll down to "Installed On Apple Watch" and see if PK Rewards appears in this section. If it appears in this section, this means it's properly downloaded to your watch and you should be able to start a workout!
If it does not, scroll further to "Available Apps" and see if it appears in this section. If you see "Install" next to PK Rewards, simply click that and it will begin downloading! You may also see it in a Loading state or Downloading state (see below).
If you get stuck in the Loading state, please try deleting the app and re-downloading it from the app store + make sure your watch is on, nearby, and Bluetooth is turned on (both on your phone and your watch).
