Disappointingly this issue is not fixed for me. I just updated to 27.09 after the assurance that the issue had been resolved in this thread: RE: Is garmin doing something about is connectivity issue with shwinn ic4
I can confirm that for me, the issue is still there. No change in behaviour. For a description of the issue refer to the old thread, as from what I can see from my testing it is exactly as it was.
If anyone else can feed back their experience that'd be great.
