Bluetooth connectivity issues after updating phone to Android 10

After Android 10 update on my OnePlus 6T, my Samsung Gear S3 kept loosing the bluetooth connection with my phone. I cleared the phones cache, removed and reinstalled any Samsung related apps, wiped my watch and did a complete new connection with my phone. Still the same constant issue with dropped bluetooth connection.
Then, as a last attempt to resolve this, I uninstalled the Watchmaker app from my watch and haven't had any dropped bluetooth connection since! Can you guys please have a look at what might cause this? Before the updated android version arrived to my phone I did not experienced any bluetooth connection issues.
