I'm experiencing strange behavior of my Tempe sensor on my 735XT.
When I start the running activity, the sensor can not be found, no matter how long I wait, no matter how close they are together.
On the Hike activity it does find the Tempe sensor after a few minutes.
Using the search for sensor en the settings menu also doesn't find my Tempe.
The problem seems to be with my 735XT as I also hae an Oregon600 that reads the Tempe's data instantly.
Any clues what to do with this?
