Wear OS latest version can not load

Hello,

I have the latest version 1.1.6 of Locus Maps for Wear OS on my Fossil Gen 5 watch.

I also have the latest version 3.49.0 on my Android 6.0 phone LE S3, model LEX626.

The phone version works well.

I am not able to run the watch version. I have the phone app open, I have gps on, the phone is paired to my watch and still the watch app has this error message : Connection Lost. Please check Bluetooth settings and try again.

What should I do differently? Where is the issue?
