Galaxy watch 3 disconnecting from Bluetooth on Note 20

[userjAtJ8yCda1]

I keep getting a message saying my watch has disconnected via Bluetooth from my note 20. I have a galaxy watch 3 and have tried clearing my gear app cache and restarting my phone, that worked for about a day, but it's started doing it again. My watch is also up to date with the most recently update. What can I do to solve this?

Try to unpair and pair it again...

I'd try to unpair and pair it again 

or submit an error report if it keeps disconnecting even after unpairing

An app that is responsible for connection is being optimized by battery usage. It preserves battery life by limiting what apps can do in the background. I remember when setting up a watch, the app(galaxy wearable) would ask me if I want to keep the app from being optimized and user then would tap yes or no. Saying yes to that prompt is better.

Go to settings, then apps and search for Galaxy. In the list see if you have something like galaxy watch plugin. Tap on it and go to battery. Here is an image of what mine is set to.
