Venu 2 Software Version - 17.04 - Disconnecting from phone

Good morning team,

After I've updated my watch with new SW it keeps disconnecting from the phone. Occasionally what I can see status of the Watch is connected despite on the phone Bluetooth is off.

After forgetting the watch and paring up again it can work for a day, but then issue will occur once again.

Phone is iPhone 14Pro with SW 17.1.1

Any advice?
