Hey @pinkvenom,
Thanks for posting in the Community and for sharing these details with us. As it seems that you've explained a few different issues, let's tackle this bit by bit.
Firstly when it comes to Smart Shuffle it's worth noting that you can activate it in any of the playlists that you've created or in your Liked Songs, however, it's not possible to activate it when you've started a Spotify Radio. If you're instead referring to the Shuffle function which you mentioned it only plays the same artist tracks within the Radio playlist, does this happen with other playlists as well? Keep in mind that Shuffle prioritizes the songs that Spotify perceives you enjoy the most and this can be the reason why you might notice that some songs are repeated. I recommend checking out this thread where other users have shared their comments on the Shuffle function.
Next, you mentioned that the playlist will end when connecting to a new device, but does this happen immediately upon connecting or after some time and have you tried clearing the queue or any other troubleshooting steps? It'd be very helpful if you could let us know what you've tried so far, so we can avoid repeating any steps. You can check what other users have explained here and if it sounds similar, you can post a comment in the thread there.
Lastly about the Jam session, is the person able to Leave it or is it stuck? What about on another device, how does it look there?
If you haven't done this already, I recommend starting with a clean reinstall of the app on the Motorola as there can be some corrupted cache which may be causing performance issues, so it's worth testing if it'll make any difference. You can check out and follow the steps here.
If the issues continue, it's a good idea to also search for similar threads in the Community where other users have shared the same/similar experience or even posting separate threads about each of the issues you've explained here in the relevant Help boards. As they're different, this way it'll be easier for us to investigate each of them separately.
We appreciate the cooperation and keep us posted on how it goes 🙂
