1. I have discovered that presently the Guide will update but only for the channel that the TV is currently tuned to. I'm unsure how the guide worked in the past with all channels filled but maybe there is a clue there. 3. Clearing cache did not fix it. Reset to Original Settings will wipe out all settings & is too drastic to contemplate!

1. For well over a year the Antenna Channel Guide has been incomplete. Is there a way to manually update the guide? The Prime app has suffered from two problems: 2. No subtitle option on movies, fixed by app uninstall/reinstall. Is there an easier fix? 3. 4K movies downgrade to SDR or SD momentarily, app uninstall/reinstall did NOT fix this? TV software is upto date. Internet speed is good. Cache has been cleared by power disconnect/reconnect. I have not tried Reset To Original settings, will that wipe out antenna channel & HDMI input name customizations? Thanks.
