Hi,
My Sofabaton U Series Remote was working with my ROKU Express 4+ this morning and after what appears to have been an update of the Roku Software which also changed my Wallpaper, the Sofabaton stopped working altogether.
All the other devices, TV Soundbar, etc., work just fine.
Please advise what this update caused and fix it. This is on ROKU not Sofabaton. Don't try to push sell your remotes. : )
Not familiar with the Sofabaton, but I would check to see if there is a firmware update available for the device. Maybe that might fix the issue.
Wallpaper updates happen independently of firmware updates (Settings/Theme/Seasonal wallpapers or Sponsored wallpapers = Off if not wanted), though its possible wallpaper may be reset to the default state with some firmware update scenarios.
Unless it was a firmware update (Settings/System/Software Update/Last Updated = ?) or remote firmware update (N/A since you arent using the Roku remote) then remote functionality shouldn't be affected.
If you haven't already rebooted your Roku device (complete AC power off) then you should do so.
Otherwise you can try re-configuring/re-setting your Sofabaton (or learning from the Roku remote in IR mode).
