Don’t shoot the messenger. My wife enjoys working out to these exercise videos on TiKTok. I have shown her how to mirror her cell phone to the Firestick. But, she insist that the app must be available. Amazon does have a TikTok TV app but it went dark in September of 2025. Tried Download the TikTok app for Android and iOS - Get official latest version in Downloader but after downloading it and opening it up it stated there was a network error.
