Found a problem with 22.22 version : When I finished a run activity, stress levels are "Recovery after exercise, try again later", which is normal. But, just after my run, I usually take a shower and I put down my watch. Then, when I put it back on my wrist, the stress levels on the graph of Body Battery and Stress widgets have disappeared.
The little pie chart in the Stress widget still have the data of the day, and of course all datas still in Garmin Connect
