Vivoactive 3 + external HRM won’t connect for Swimming

I’ve been trying to swim with my Vivoactive 3 + external HRM but it won’t connect at all.

any suggestions?

ANT+ or BLE radio waves do not travel through water. So there is no way to connect an external sensor to a watch under water.

It worked when I swam with my FR25 that’s why I’m wondering.

The FR25 did not have a dedicated swim profile, AFAIK. You can achieve a similar result on your VA3 if you select a non-swimming mode. The watch will connect to an external HR sensor and will show HR data as long as you keep both the watch and the sensor above the surface.
