There have been a ton of beta updates recently (e.g., 6384, 6404, 6408, 6415, 6441, 6465) with little or no explanation of their purpose other than vague references to device connecting. So far, I have been finding their is some irregularity and unpredictability in connecting, particularly to BT HRM's. We use both a Polar H7 and Wahoo Tckr. I generally do not have issues connecting to the trainer (Neo2T and Fllux2), but sometimes it is very slow to connect to the HRM even though TDA identifies it as an available device. Today, it did not want to connect to the Wahoo Tickr at all. I restarted the Device search function a number of times as well as restarted TDA. Finally, after trying various approaches, it connected. I really do not know what I did to either to cause it to connect or not to connect. I think I have noticed that I should connect to the trainer before trying to connect to the HRM, although I can't swear to it.
