Since latest watch software update, I cannot recallibrate blood pressure monitoring. Constantly fails because "signal weak". Back of watch is clean, have tried varying degrees of watch strap tightness (to ridiculously tight watchstrap) with same error. Watch is fully charged. Reset phone and watch. Same issue.
Given that is a main reason that I bought the wearable, and given that have had no issues before indicates there is a problem with the software?
