After upgrading to Android 16 and resetting my GW5 pro. I can not connect the watch to my Samsung account. 
Here is what I have done with no success. 
1. Restart watch and phone 
2. Verify Date and Time on phone and watch.
3. delete Galaxy apps on my phone and reinstall 
4. re-paired watch and phone.
5. Reset watch
6. Reset my phone to factory and watch again. 
7. Plus I was able to reset my watch and connect it to an Android 15 phone and it connected to my Samsung account with no problems.
8. Also I am having trouble with my Galaxy buds FE not being able to connect to my Samsung account.  
9. New problem. Update Samsung Acc... app on my phone through the settings menu on my phone. Now when my phone connects to my Android 16 phone it crashes my the GW5 app on my phone.

What am I missing?
Has anyone installed a new watch on an Android 16 or 16 betas without problems?
