How do I set WandelWeb to Unrestricted on a Xiaomi, Redmi or POCO?

Xiaomi, Redmi and POCO

1. Open Settings > Apps > Manage apps > WandelWeb.
2. Tap Battery saver and choose No restrictions.
3. On the same screen, turn on Autostart.

Tip: don't swipe WandelWeb away from the recent apps overview during a hike. On some Xiaomi phones the app will stop anyway. You can also lock WandelWeb in that overview with the padlock.
