Apps missing from home screen

I have a few Roku add-on channels.

This afternoon, they no longer show up on the home screen. To use them I have to go through the Roku channel.

Is this a temporary glitch or a permanent PITA?  lol...

Just wondering. Having an option to subscribe via Roku was nice, but I don't want to have to jump through additional hoops to access my services. Three of them are annual. Renewing depends on your answer here.

Thanks.
