Unassigned Sensor At Start of Round

I have the identical problem – please also each out to me when you have a solution. 

I have this exact same problem. Same two clubs, beginning of each round. Looks like you have had this problem for months with no actual resolution. Very frustrating. I am on an epic 2 with the latest software if that makes any difference.

Exact same problem as well. Although the sensors are paired with S42 watch, the watch pushes notification, that sensors are not assigned. Unfortunately, it doesn’t say which out of the 14 in use. Further on the course to start the round of golf, you can click away the messages, but the sensors are not tracked. So you need to assign your shots manually again on the watch. 
Would appreciate your support, because like this the sensors are not useful.
