I received a response from Garmin advising me I was using an unsupported browser in Chrome... Problem is I use at least 4 different browsers on 3 different devices and the problem is still the same. I advised them of that today so am waiting to see what they say... Below is the info..
for goodness sake, how on earth can it be a Chrome issue when the problem manifests itself in GC Mobile after a wireless sync (i.e. without going anywhere near a Chrome browser!!).
I also had a response from Garmin, requesting a screenshot, which I have duly sent, even though it was attached to my original message...
