Unable to sync Versa 2 with OnePlus 6

[3101010]

It's not my first time to ask for help in the same topic. 

I bought the Versa 2 watch in January and the time my phone and watch got connected was only 10 days. 

They can't sync for the past 2 months and I don't see any help on this.

I restart my phone, delete and reinstall the app many times. Everytime I did that, they got connected/sync for 10 min then it failed again.

Then I start to restart my watch and factory reset it. Same result.

This is even worse than getting a no brand Android watch. Very disappointing.

Hi @3101010, it's nice to see you again participating here in the Community Forums! Sorry for the delay in responding your post.

Thanks for bringing this to our attention and for troubleshooting your device before posting, I understand how frustrating sync issue can be for you. If you haven't already done so, I recommend you to check how the syncing procedure works here and see if there's a missing requirement on your OnePlus 6 that's preventing the syncing procedure to be completed.

Then, you can move forward to the troubleshooting steps that are specified on: Why won't my Fitbit device sync? and let me know how it goes. 

Keep me posted, I'll be around if you need anything else.

Is there any way to receive notifications?

it keeps saying notification service is not available. i need to restart my
phone to make it work. But I've restarted it numerous times.
