My roku is sending the same Amber Alert every 5 minutes. I know it is not the Emergency System because only got one on my phone. Tried rebooting it but it has been 30 minutes and still going off.
Is this happening on the Roku home screen or across multiple apps? If not, then I think it is something within a specific channel/app. I’m not aware of Roku itself having an Amber alert feature.
Perhaps it is something your television is doing, independent of what input you have selected. (??)
