@dLightz No problems here, I am using the exact same setup and have no issues. Sounds like this might be specific to you. I would try uninstalling Shapr3D and reinstalling it (this usually takes care of annoying issues like this for me).
I have a similar problem. When listening to music or watching Netflix in the Picture in Picture mode, the playback stops when as soon as I open the Shapr3D App.
