Hello,
I don’t know if it’s an issue, but after one week I finally found (alone) the solution, I created a new distributor certificate with only DUID of my Watch, and without the DUID of emulators…
I seem to remember that 2 years ago when I connected my watch for the first time, it was necessary to put the DUID of the emulators in the distributor’s certificate to be able to use them (but I am not sure …).
