Thanks for the reply MattF. Shotscope did get back to me in 48hrs but with the suggested re-set and re-boot from the website instructions.
Although I had completed these steps several times already without success, I followed them again but this time went a step further. The very misleading part of these instructions (which are on the website), is the phrase "Complete on boarding'.
As I was not sure the watch was working, I had not 'Set up my Bag' with the tags and therefore did not want to proceed beyond this stage. As the phrase "Complete onboarding' didn't mean anything to me
