@gavs82008 This is a (Sony) Android TV with the installed app (v4.0.0).
Things I’ve tried that didn’t work :’(
Checked for updates in the play store, and for the TV itself.
uninstalled and reinstall the app.
restarted the whole TV
One thing to try, which is a bit extreme, is to set the fire stick back to factory settings. Might resolve the issue.
Is the fire stick on Wi-fi or Ethernet? Might perform better on Ethernet. Although not sure if it will resolve the error in question.
