Hi there! I see you're getting a black screen when trying to start a meditation on your iPhone. That can definitely stop you from enjoying your session. Could you tell me a bit more about when this happens? For example, does the app load normally before the black screen, or does it happen right away when you tap to start meditation? Also, have you noticed this only with certain meditations or all of them?

Meanwhile, here’s a step-by-step approach we can try to fix this:

1. Force quit and reopen the app: On your iPhone, swipe up from the bottom (or double-click the Home button if it has one) to bring up the app switcher. Swipe the Headspace app off the screen to close it, then reopen the app.

2. Check your internet connection: Since some meditations might need to stream, make sure you have a stable WiFi or mobile data connection.

3. Restart your iPhone: Sometimes a simple restart clears temporary glitches. Press and hold the side button and either volume button, then slide to power off. After it’s off, hold the side button again to turn it back on.

4. Update the app: Go to the App Store, tap your profile icon, scroll to Headspace, and see if there’s an update available.

5. Reinstall the app: If the above steps don’t help, try deleting Headspace from your phone and reinstalling it. This can clear out corrupted files.

6. Check iOS version: You mentioned you have iOS 18.5, which should be compatible, but make sure your phone isn’t in any kind of beta or developer mode that might affect app behavior.

If these don’t resolve the issue, sometimes black screens or freezes can be related to account sync issues or app bugs, in which case we might need to check for reported problems or escalate the issue.

Can you please let me know if you’ve tried any of these steps already? Also, any extra details you provide will help me zero in on the best fix for you!
