Hi! I understand you're having trouble seeing the full speed control on the Overcast app on your iPhone 6s because of a large left margin. Let me help you with that.

This issue seems to be related to some recent updates where the UI layout does not fit well on smaller or older iPhone screens like the 6s, causing controls to be pushed or clipped off the view.

Here's what I suggest trying step-by-step:

1. Check for App Update: Sometimes, developers release patches shortly after bugs appear. Make sure your Overcast app is updated to the latest version via the App Store.

2. Restart the App: Close Overcast completely (swipe it away from the app switcher) and reopen it to see if the layout refreshes properly.

3. Restart the iPhone: Power off your iPhone 6s and turn it back on. This can clear temporary glitches affecting app display.

4. Adjust Display Settings: Sometimes display zoom settings on iPhone can affect app layouts.
- Go to Settings > Display & Brightness > View (Display Zoom) and see if it's set to Zoomed.
- If it is, try switching to Standard and see if this improves the layout in Overcast.

5. Reinstall the App: If the above don’t help, try deleting Overcast and reinstalling it. This can clear corrupted settings or resources causing display problems.

6. Report the Issue: If the problem persists after all these steps, this is likely a bug related to the app's UI on smaller screens like your 6s. You can send feedback to Overcast developers through the app’s settings under Help or Send Feedback. Providing details about the large left margin and which version of iOS and Overcast you’re using helps them fix it sooner.

Because this is a known layout problem on older/smaller iPhones reported by other users recently, it's possible the developers are already working on a fix1.

Would you like me to guide you through any of these steps? Are you seeing anything different in your app interface that might give us more clues?
