i just picked up an AW2 today, and made use of 'hey siri'. After a few hours it stopped working. I tried everything, including re-pairing, but it never worked again. Managed to fix problem by doing a complete erase and setting up as a new watch. Again, it worked for a couple of hours but has now stopped working again. Any ideas? --- Post Merged, Oct 14, 2016 --- To be clear - it works if I hold the Digital Crown, but just using the hey Siri command upon waking does nothing. I really don't want to erase everything and start from scratch for the second time in a day!
