Connection & Sync Problems

Updated August 1, 2026Connection & Sync Problems
GapFix needs an internet connection for most things: generating and updating your 12-week plan, loading lessons and Boosters, and keeping your progress in sync. Your Day-1 lesson is pre-cached so it opens instantly, and a full offline mode is coming soon — but for now, a flaky connection is behind most loading problems.
First checks
- Make sure Airplane Mode is off and Wi-Fi or cellular is on.
- Open another app or website. If nothing loads anywhere, the problem is your network, not GapFix.
- Toggle Airplane Mode on for ten seconds, then off — this resets your device's radios.
- Switch between Wi-Fi and cellular to rule out one connection.
- Restart your device.
If GapFix specifically won't load
- Force close the app and reopen it.
- Office, school, and public networks sometimes block app traffic with firewalls or captive portals. Try cellular or a different network.
- VPNs occasionally interfere with app connections. Try again with the VPN off.
- Very rarely, the issue is on our side. If every other app works and GapFix can't connect, wait a few minutes and try again — and if it persists, email help@gapfix.app.
Progress not syncing between devices
Sync depends on being signed in:
- Anonymous use is device-local. GapFix starts without an account, and until you sign in, your progress lives on that one device. Sign in with Apple, Google, LinkedIn, or email on both devices to sync.
- Check you're on the same account on both devices. Your Profile shows which account you're signed in with. Signing in with a different provider than you originally used lands you in a different account — which looks exactly like "my progress vanished".
- Give the first device a chance to push. Open GapFix on the device where you did the learning, on a good connection, then force close and reopen on the second device.
Streaks and timing
GapFix counts a day against your local midnight. If your streak or today's progress looks out of date right after finishing a lesson, give sync a moment and revisit the Home tab.
Still stuck?
Email help@gapfix.app with your device model, iOS version, whether you're on Wi-Fi or cellular, and what exactly won't load. That detail gets you a useful answer much faster.
