How do I reinstall the Play on Roku channel?

Roku ECP /query/device-info false

I cannot cast media to my Roku via the Roku App. I could and then it just stopped.

When I curl http://${ROKU_IP}:8060/query/device-info it returns:

<?xml version="1.0" encoding="UTF-8" ?>

…
false

What is the method for reinstalling Play on Roku?

Is the only solution to factory reset? (I have not tried that yet, but I assume that would do it.)

I think I fixed it.

If anyone else stumbles upon this; I fixed it by running curl -d ā€˜ā€™ http://${ROKU_IP}:8060/launch/11?contentID=15985

15985 is the id of Play on Roku.
