Lactate threshold: different pace in watch and app

Hi all,

I have done today with my Forerunner 945 LTE again a lactate threshold Workout Test. It works fine and I have a new pace (faster!) and the same pulse.

It shows in the watch, also with a date. So fine. The predection is a bit better.

What I do not understand: in the Garmin App Connect I do not see this new measurement. (I synchronized.) It shows old values (pulse and pace) from 2 month ago. The pulse is fine, but the pace is wrong.

So, is this a bug? My app and watch are updated at the newest versions.

Thanks for any help.

Martin
