Hi all, Since the August 2025 update, I've noticed Thunderbird is no longer syncing some of my Gmail folders (mostly labels I created manually in Gmail). The inbox syncs fine, but custom labels show up empty or don’t appear at all. Things I’ve tried: Removing and re-adding the Gmail account using OAuth Checking Gmail’s IMAP settings — all folders are selected for sync Rebuilding folder index files in Thunderbird I didn’t have this issue before the latest Thunderbird update. Is anyone else seeing this? Could it be a bug with label handling or IMAP path prefix? Any advice would be appreciated!
