Hi there! I see you're experiencing crashes and issues with uploading in the MoShow Slideshow Maker app on your iPhone running iOS 18.7. Also, you've tried reaching out to support via email but haven’t received a response yet. Let's work together to get this sorted out.

To start, can you tell me a bit more about when the app crashes? For example:
- Does it crash immediately on opening, or during a specific action like uploading or saving?
- Are you connected to Wi-Fi or cellular data when trying to upload?
- Have you recently updated the app or your iOS version before this started happening?

Meanwhile, here are some general steps you can try that often help with app crashes and upload problems:

1. Restart your iPhone: This can clear temporary glitches.
2. Check for app updates: Go to the App Store and make sure MoShow is updated to the latest version.
3. Clear app cache or reinstall:
- Unfortunately, iOS doesn’t let you clear cache directly, but deleting and reinstalling the app often helps. Before deleting, make sure you have saved your projects or backed them up if possible.
4. Check network connection: Ensure your internet connection is stable. Try switching from Wi-Fi to cellular or vice versa.
5. Free up storage space: Low storage can cause app issues; verify you have enough free space.
6. Close other background apps: Sometimes too many apps open can affect performance.

If you’ve tried some of these already, no problem — just let me know which ones, and we can dig deeper. There might also be some compatibility or bug issues that the developers need to fix; I can help you escalate it if needed.

Does the app crash during specific steps or in general? That detail will help pinpoint the problem better.
