Pairing Failed (Internal alert) – Updated to WatchOS 6 B2 before updating to iOS 13 B2

Same issue here. I tried all the solutions offered in this thread:

None of that helped, unfortunately.

I had this same issue and finally resolved it today. First of all, you have to be on iOS13 Beta 2 on your iPhone for WatchOS 6 Beta 2 to work. If you did like me and installed WatchOS 6 Beta 2 before iOS 13 Beta 2 there is a fix:

1.Turn off the Apple Watch.

2. Restart the Watch and press and hold the side button when the Apple logo appears. Do this until it prompts you to erase the watch.

3. Select to erase the watch.

4. Install iOS Beta 2 on your iPhone and restart afterwords.

5. Pair the watch to the iPhone and you should get passed the "Pairing Failed" issue.

This is what finally worked for me, hope it helps.

Thanks so much.

Thats the only way to fix.

Now its working.

Thanks.

Thank you so much, I had an issue & now fixed.

Funny, this procudure only works, if done from shutdown->startup.

If done by holding sidebutton & crown, force-click and select it, it does not work.
