How do I leave a channel?
You may choose to leave one, or a number of channels because you’re overwhelmed by the amount information you’re receiving.
Choose the channel from the app menu (the three lines in the top-left of your screen) or by using the “Search” facility on the Discover page.
Select the channel you wish to leave and tap on the three dots at the top of the channel page in question
Tap again on the “Leave channel” option
Confirm that you do really want to leave.
You can do this for as many channels as you want in order to focus your experience on 115.1.
