Lactate threshold 46bpm?

Normally my lactate threshold is around 176bpm but Garmin Connect suddenly shows it down at 46bpm! Obviously that can't be right. Does anyone know what could have caused that? I've been using an Edge 530 for cycling and a Forerunner 935 for a variety of other activities. The 935 shows my correct lactate threshold at 177bpm so I suspect the Garmin Connect app might be getting bad data from the 530.

I tried up upload a screenshot from the app but when I try to insert it here I just get "Error".

I have the same problem. I use Edge 1000 and Forerunner 945. Lactate threshold chart jumps between 50 and 165bpm!

The problem appears to be fixed for me. I haven't seen any more anomalous lactate thresholds in the past two months. Currently it shows 173bpm, which is probably approximately correct.

Hello, I have the same problem for some time now. F5 + 530. How did you fix it?

I didn't do anything so I assume Garmin fixed it somehow.
