This is because desktop and iOS use different endpoints for Sync server. This will get fixed in next beta build

Hi,
I don't know if it's totally related to this bug, but one of my iphones did join the sync chain but then it gave me an error message that the sync server or something wasn't available at the moment so I had to try later.
On the other devices I did see the new phone.
The only thing I could do (since there was no way to unsubscribe to the chain because of this error, and the removal of this devices from other devices didn't work,
So the only thing I could do was to uninstall brave from the phone.
then I sync it up again and now it works.

The only problem is that I lost 70 tabs in the process. That would have been nice that there would have been a feature to export the tab list or the history. That would have been nice....

the build is and was 1.11.3(19.08.16.20) on iphone XR
