How does Zen browser (FF) Sync handle conflicting profiles across devices?

[baki2001]

Let’s say I have my home computer, where I logged in with my Firefox account on the Zen browser and turned on sync. Later, I set up Zen on my work laptop and, after finishing the configuration, I also turn on sync. What does the browser use as the source of truth in this case? It seems like there could be a merge conflict since two different profiles that don’t match are trying to sync.

Will one of the profiles get overridden?
