Reproduction steps

Google Reader account pointing to a self-hosted Miniflux instance (via its Google Reader API).

Steps to reproduce

1. Open the unread list - e.g. 515 unread.
2. Tap Mark all as read -> count drops to 0.
3. Open the Miniflux web UI in a browser → still shows ~1699 unread.
4. Pull-to-refresh in Read You → count jumps to ~1796 unread.
5. Tap Mark all as read again → count drops to 0.
6. Pull-to-refresh → count rebounds to ~515; Miniflux web UI shows ~475.
