+## [Unreleased]
+
+### Fixed
+
+- **Google Drive**: sync now works for folders inside a Shared Drive (formerly Team Drive). The Drive API `files.list` calls were missing `supportsAllDrives` and `includeItemsFromAllDrives`, so Shared Drive contents were invisible and the sync reported "nothing to do". File downloads/exports now pass `supportsAllDrives` as well.
+
 ## [0.3.6] - 2026-05-28
