Excluded Folders entry not saving on Android

Bug reports

Did you read and follow the Troubleshooting Guide? Yes

Steps to reproduce

  1. On Android, go to Settings > Sync > Excluded folders > Manage.
  2. Type a new folder path into the input field (e.g. Archive).
  3. An autocomplete dropdown appears showing matching existing subfolder paths as you type.
  4. Tap Done.
  5. Also tried with a trailing slash (Archive/) in a separate attempt, same result.

Expected result

The expected path is added to the Excluded folders list and shows up under Settings > Sync going forward.

Actual result

The new entry does not appear in the Excluded folders list afterward. Reopening Settings > Sync shows only the folder(s) that were already excluded before the attempt. Confirmed via screenshot of the Sync settings page taken immediately after tapping Done both times (with and without the trailing slash).

Reported to support first (ticket #149971), and reproduced there with screenshots of the input screen (showing the autocomplete dropdown while typing) and the Sync settings page confirming the new entry never persisted.
