Hello @leparker
Thanks for reaching out here in the Community!
Firstly, please be advised that this thread is about your apps that don't load. If you need further assistance with another issue, please create a new thread for that concern.
You've mentioned that your channels aren't loading after updating your Roku device. Do you receive an error code or message when launching the apps or did they just automatically go back to your home screen? Have you checked if all the channels are affected? Please let us know as well the model number of your device. It can be found in Settings > System > About.
With more information, we can assist you further.
All the best,
Kariza
