Bluetooth connection keeps disconnecting

I've got my Venu 3 since yesterday. Before, I had Venu 2 and had no issues with that model. The new watch often loses bluetooth connection for some time, sometimes I need to re-pair with Garmin Connect. 

Garmin Venu 3, sw version: 6.21
Phone: Huawei P30 Pro

I am aware that there are some issues with Huawei phone and Garmin watches bluetooth connectivity but I had no issues with Venu 2, so I am not sure if the issue is the phone or watch itself.
