Forerunner 245 Music: After update 4.40

After update to version 4.40 Speed, round and tempo notifications no longer work from watch to bluetooth headphone.
The CellPhone stays at home while running (its the interaction watch - Headset).
I can still hear the music (spotify) but no notifications anymore. 
Meanwhile I update to beta version 4.41 ... doesn't help.  Almost two months now!
I did sent already 2 e-mails to Garmin-Support and I called two times.
