Broadcast renewal

I am a beginner. I made a live tv application. sometimes there can be problems with broadcasts. When I change the broadcast link, I want to update the broadcast by adding a “refresh” button so that it changes on the devices where the application is installed. can you help

you can try this
whenever that refresh button is pressed, close the screen and then reopen it. Doing this, all the data/links will be refreshed and also send a push notification to your app, to tell the users that you have added a working link so users should click the refresh button
