It seems to ONLY affect my watching BLAZE TV programs on ROKU. IF I switch to PLUTO & watch BLAZE on there the problem doesn't seem to show up!
Normally when encountering an issue with a standalone Channel/app like the BlazeTV, it is often recommended to see if available on other Channels/apps like Pluto or the Roku Channel.
Sometimes these Channels/apps just experience issues and need to be addressed by their developers. Usually either contact the Channel developer, or wait a few days to see if resolved.
Really the only thing an end user can do to see if they can resolve issue is to Remove Channel, Restart the Roku device to clear cache, and then Reinstall Channel (in that order).
If doesn't resolve issue, then it is an issue that usually needs to addressed by the Channel developer.
