Firefox Android does not sync massive password deletions made on Firefox desktop?

Got a firefox/mozilla account from day one, using it to sync all my settings/passwords etc between my desktop/laptop/office system as well as my Android mobile. Some days ago I decided to delete all my passwords from Firefox sync. To do so I just elected to delete all passwords, from the password page. Things went just fine and my action was replicated to my Windows Firefox installation, resulting empty password lists everywhere. Except my Android phone. Even though I've triggered even manually a sync, all passwords are still there. I '''know''' that sync worked just fine with credential pair additions/removals/changes, made from either the mobile or the desktop side of things. Is this by design maybe? If so, I presume that I can uninstall Firefox from Android, and then reinstall and connect to my Mozilla account. But I'm curious whether there's something else at play here. I'm using the latest Mozilla version everywhere. On Android I utilize the ublock origin and I still don't care about cookies extensions.
