If the canvassing map is showing a blank screen, spinning indefinitely, or not displaying pins, these steps will fix it.
Location permissions — The canvassing map requires location access. On iPhone: Settings → Scaffold → Location → While Using App. On Android: Settings → Apps → Scaffold → Permissions → Location → Allow.
No internet connection — The map requires an active data connection to load tiles and sync pins. Check that you have cell service or WiFi.
Browser/app outdated — If you're on an older version of the PWA, try refreshing or closing and reopening the app.
Too many pins loaded — In areas with very high knock density, the map can slow down. Use the date filter to limit the view to recent activity.
1
Force a refresh: on mobile, close the Scaffold tab completely and reopen it. On desktop, press Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac).
2
If the map still won't load after a forced refresh with good connection, go to Settings → App → Clear Cache and try again.
For canvassing in areas with poor cell coverage, switch to offline mode before you lose signal — the map tiles will be cached and you can still log knocks, which sync when you reconnect.
