Changes look great, thanks for fixing this.

r+ we will need client-side patches for iOS and Android to execute this I think, but can get there easily since we've done this before and we don't have breaking API changes here.

I think the mobile clients are already calling RemoteSettingsService::sync() which means they'll get this automatically. So we should double check that for sure, but maybe we don't need to land any other patches.

In the worst case scenario, we will run the sync one day after the fix lands. This should be enough.
