### 1.0.6 — 2026-07-10

- New in-app status banner: if Countdown Days is ever having trouble or undergoing maintenance, you'll see it right at the top of your countdowns — no more wondering why something isn't syncing. Tap for details, or dismiss it once you've seen it.
- Behind-the-scenes reliability improvements.

### 1.0.5 — 2026-06-27

Stability fixes:
- Fixed an issue that could repeatedly sign you out or show a "session expired" message. Sign-in is now reliable.
- Fixed your countdowns not loading after signing in — your events sync properly again.
- The app now stays signed in through brief server hiccups instead of overreacting.

Thanks for your patience and for the reports!
