I've noticed a problem with the watch detecting sensors during multisport activities. During my triathlon it was particularly problematic as it didn't find my vector 3 pedals until about 2 miles into the bike leg. Is this a bug? I have noticed it during indoor brick sessions with sensors being detected few minutes later but normally it's sensors that aren't associated with the activity (ie turbo trainer during a run) so it hasn't been a big deal but I don't want it happening again in a race.
