Before switching to Inbox with my Gmail account I had certain labels in my Gmail account.
Then I switched to Inbox, added some other labels and set them as bundle. that works and syncs correctly 2-way with Android device.
However the old labels (which I was using before switching to Inbox and that I DELETED from Inbox from Chrome <-- desktop) had to be manually removed from Inbox for Android as well
Any clue? Is this a bug?
