Ratings & Reviews
This update makes Sustainers clearer and smoother to use:
- Refreshed sign-in screen — it's now obvious you're signing in to Sustainers, with a quick way to get help if you can't access your account.
- You stay signed in longer, so you have to log in again far less often.
- The check-in widget now shows the Sustainers logo when you're all caught up or signed out.
- Fixed a challenge that could incorrectly show as "not started."
- Smaller refinements and polish throughout.
