@nikolai-misc Even if I unplug the hub to which my Flic was previously connected, my Flic still cannot connect to my MacBook. So it's not the case that two different devices are competing over the connecting, since the other device is unplugged and disabled. Rather, it seems that the Flic itself still thinks it's connected to a hub from which it has been deleted. And as a result of that, I can't connect it to my laptop at all. Very frustrating!
@oskar That has not solved the problem. In my case, I deleted the button from my hub BEFORE trying to connect it to my laptop, and I experienced the same problem (connecting, the circular progress bar gets 99.999% filled, one pixel of progress remaining, and nothing happens).
This continues to happen with Flic buttons that are definitely not connected to existing hubs, and it's pretty frustrating (I've dealt with this a lot over the past few months). It feels like if you decide to repurpose a Flic button from one routine to another, you have to throw it away and buy a new one, which is very discouraging due to the cost. If it won't connect to my devices, what good is it?
