TuneIn Plugin, Not Saving Favorites

Using the TuneIn plugin (updated:19-3-2018) on Volumio 2.411 running on a rPi3. I navigate to a specific TuneIn radio station and click “Add to Radio Favourites.” The station does not appear in either Browse/Favorites or Browse/Web Radio/Favorite Radios.

Can confirm that and it has been so for a while

I agree this bad behaviour.
Is a new version planned?

Are there any updates with Tunein and ability to add & save Favorite radios on Tunein?
