RaceRender lists Kiwi 3 for IOS & Android now but the Galaxy S7 connection fails

The Kiwi 3 is connected to the Porsche Cayman port and to Samsung Galaxy S7. I can connect and setup channels the connection sometimes but lost the link after setup. A YouTube video shows certain combinations of channels successful (for that car).

When I used it at the track, I captured no OBD data and the phone was extremely hot, ran out of battery, and lost the third session. The PLX app will connect reliably and yes, I do disconnect it prior to the TA connection attempt.

Can this issue be corrected? Is there a functioning channel group or should I return the Kiwi 3?

Thanks, Steve
