Have you moistened the pads?
Garmin are decent with their service but I can't say who will be faster.
All washed and moistened before each use ¯_(ツ)_/¯
Do not start me on the heart rate monitor intermittent function after I started using it recently. Doubt very much yours is broken or the batteries.
How did you wash it? The salt in sweat actually kills it, so it needs to be cleaned properly, irritatingly.
