Why is the mobile header in Webflow working on my co-worker's iPhone but not on mine?

If your mobile header is working on your co-worker’s iPhone but not yours, differences in device settings, browser versions, or cache could be causing the issue. Follow these steps to troubleshoot.

1. Check Browser and OS Version

• Ensure your browser is updated (Safari, Chrome, etc.).
• Compare iOS versions between your device and your co-worker’s. Older versions may introduce inconsistencies.

2. Clear Cache and Hard Refresh

• If using Safari, go to Settings > Safari > Clear History and Website Data.
• If using Chrome, go to Settings > Privacy > Clear Browsing Data and select Cached images and files.

3. Test in Incognito Mode

• Open a private browsing window (Incognito in Chrome or Private in Safari).
• If the header works, it's likely a caching issue. Clearing the cache should resolve it.

4. Disable Browser Extensions

• Some extensions, like ad blockers or privacy-focused tools, can interfere with Webflow sites.
• Disable extensions and reload the page.

5. Test on Different Network or Cellular Data

• If your phone is connected to Wi-Fi, try switching to mobile data (or vice versa).
• Some network settings or firewalls may block parts of your Webflow site.

6. Recheck Webflow Breakpoints

• In Webflow Designer, go to the mobile and tablet breakpoints and verify that styles and interactions apply correctly.
• Ensure no custom code (like display: none; or media queries) is unintentionally hiding the header.

7. Check for JavaScript Errors

• If you added custom JavaScript, a script error may be preventing certain elements from displaying properly.
• Test by removing and re-adding scripts under Project Settings > Custom Code.

Summary

First, verify browser updates, clear the cache, and test in incognito mode. If the issue persists, check Webflow breakpoints and any custom JavaScript. Switching networks or disabling extensions may also help.
