I recently purchased a Fenix 6X Pro Sapphire and after the first night, the watch is no longer recording my sleep. I have 10.10 and 7.11 updates installed and checked all my settings including the battery saver. Could a different watch face I downloaded affect the sleep recording? I tried resetting after the software updates but still no sleep tracking. Any ideas please? I'm happy to share my data and want this resolved as it was one of the main purchase reasons.
