I am testing the beta now. I have experienced the white screens like the others, and had the black screen issue in the past. This always seems to happen after I return to the app after an extended period. i.e. It is always running on my iPhone, and music is playing, but I am not actively using the app. If there is anyway that I can be of additional help on this issue, please let me know, I am technical.
On the upside, the response times on the app are noticeably better, especially when I first switch back to the app and it needs to reconnect.
Stephen, is there a specific place where you want this feedback for the beta, or is this forum best. I did not see any avenue for submitting through the beta or Test Flight.
