Roku is currently rolling out a new version of its operating system, going from version 10.0 to 10.5. Roku menu path Settings > System > System update will show your currently installed version number and when it was installed. Does the date correspond to the beginning of this problem?
While there, you can press Check now to see if there is an available further update and install it. This should also update any channel apps that have pending updates.
