No fix yet. But if you have 3D Speed and 3D Distance enabled you can try to disable them. It made the delays shorter for me. But you will loose distance if you run on tracks with much elevation changes. I think that you also should register a support case to Garmin about it. To give them more feedback of the problem.
How i do that?
In the settings for the Run activity.
I open a case in garmin.
They ask for files from my watch.
I will update.
I have the same feelings. In the past when I had 920xt change of pace was very quicly. In my fenix 6x is too slow and this is annoyng.
This is very flustrsting diring runing. I remember 920xt change of Peace was very fast
I WANT the "Exact pace" field also for running!
