Hi there! I see you're having trouble creating reels with the message "invalid status code" on your iPhone running iOS 18.5. I'd like to help you get this sorted out. Before we start, could you tell me if this happens when you try to upload a video or create a reel from scratch? Also, have you tried any fixes so far?

Meanwhile, some common causes of this error can include connectivity issues, app glitches, or permissions problems, so we'll check those step by step. Here's a quick plan:

1. Check Internet Connection
Ensure you have a stable internet connection, preferably Wi-Fi, as sometimes unstable data can cause upload errors.

2. Update the App
Make sure your Reelsapp is updated to the latest version on the App Store. Updates often fix bugs causing errors such as invalid status codes.

3. Restart the App and iPhone
Close the app completely: swipe up from the bottom and swipe the app away, then reopen it. Also try restarting your iPhone.

4. Log Out and Log Back In
Try logging out of your account in Reelsapp and then logging back in. This can refresh your session and permissions.

5. Check App Permissions
Go to Settings > Reelsapp and make sure the app has permission to access Photos, Camera, and Microphone, as missing permissions can cause upload failures.

If you've tried these already, let me know which steps you've done. If not, start with these and tell me what happens. If none work, we can dig deeper, perhaps checking account or server issues.

Are you able to try these steps now and tell me what you find?
