How to update Channels DVR guide in Android TV

I made some changes to the channels that I want to show using my Channels DVR server on my Mac computer/Chrome Browser.
I then checked the broqser guide and it was updated accordingly.
But when I bring up the Channels DVR app on my Android Nvidia Shield, it is not updated with the changes I made.
How do I update the guide on my Nvidia Shield/Android TV?

Thanks!

Restart the app

That works, and my next questions is can I have the same channel show in both tuners?
Example:
I have an antenna but sometimes the Channel 2 ABC signal is too weak to pull in via the antenna tuner, and at that point I want to pull it in through Locast. I would like both options to appear in the Channels guide. I have them both designated as favorites within the respective tuner, but only one appears. I am assuming that is based upon the tuner priority setting?
Is there a way to show both in the Channels guide?
Thanks!

It is not currently possible to show both. The app should automatically try all the tuners in priority order if one is not working.

So you're saying that if I prioritize the antenna tuner, if the antenna is not able to pick up a strong enough signal, it will automatically move to the Locast tuner?

Correct
