Enabling Settings Sync nuked settings.

Type: Bug

Filing report as requested by @brettcannon in this thread https://fosstodon.org/@carlton/110340026661594602

Was using code tunnel to access local environment on iPad.

The signin there isn't 100% smooth: the callback just sometimes stalls. When I tried adding to Homescreen, I had to use the device code fallback method to get the initial auth flow to complete, but I wasn't able to authenticate to the tunnel — blank white screen — and so went back to just using it in the normal (non-homescreen/PWA) browser.

Up and running I thought to Sync Settings. Enabled this.

Shortly after, returning to my Desktop device, all my settings and extensions were gone.

Slight panic.

I was able to restore with the Sync Settings history.

Expected behaviour is for Extensions to be Merged, not overwritten (certainly not with the blank state.) Update: I see the docs have a Merge or Replace section, and there's meant to be a UI for that (according to that) but none was ever shown to me in this case.

Very sorry about this. We would like to understand what would have caused this. Since you know the settings sync data view, can you please check which machine has removed the data on the cloud?

I'm not able to dig into that. I guess I'll just close it.

I signed in on my iPad which nuked the settings on my Mac. Beyond that I can't say more.
