Where is the stream bitrate chooser?

From a web search it appears the option to choose from From different streams with different bitrates, when offered by the station, was previously in this app. Has it been removed and if so why? I purchased the pro version of this app. I need low bitrate streams when not home so I don't blow past my data cap! I don't want to go back to TuneIn but will be forced to without a bitrate option.
