After around an hour and a half or so, both these devices’ BT connections start crapping out with all 3 speaker systems that we’ve tried…an Ilive sound bar, a small JBL carry around, and Tribit cheapie speaker. Hard reboots restore the connections, but for only a very short period of time.
The connection problems are only with the Pro and Plus as both the old and new models of the ONN 4k, our MeCool KM1, our phones or the Dynalink dinosaur TV box do not display the same behavior.
