Hi there! I understand you're having trouble with video clips not playing after uploading them to the Instagram Edits app. Let me get a bit more information to help you better:

- Are the uploaded video clips not playing at all, or do they start and then stop?
- Does this happen with all videos or just specific ones?
- Are you trying this on your Windows device using a browser, or through the app on another device?
- Have you noticed any error messages or unusual behavior during upload or playback?

With that info, I can guide you through some steps to fix this. Meanwhile, here are some general troubleshooting actions you can try on your Windows device with WebKit browsing:

1. Check Video Format and Size
Instagram requires videos to be in standard formats like MP4 with H.264 codec. Large or unusual format videos can prevent playback. If possible, try converting your videos to standard MP4 format before uploading.

2. Clear Browser Cache and Cookies
Sometimes cached data can interfere with playback. Go to your browser settings and clear cache and cookies, then refresh the Instagram Edits app.

3. Update Your Browser
Make sure your WebKit browser is up to date. An outdated browser can cause compatibility issues.

4. Disable Browser Extensions
Ad blockers or other extensions can interfere with video playback. Try disabling them temporarily.

5. Check Internet Connection
A slow or unstable connection can cause video playback to freeze or fail.

6. Try a Different Browser or Device
To isolate if the issue is specific to your current setup, try uploading and playing your video on a different browser or device.

If you have already tried some of these, please let me know which ones, and I'll help you go deeper. Also, it’s worth noting some users have reported upload and playback issues with the Edits app recently, so the problem could be on the server side or a known bug too1 9.

Let me know about the additional details, and we can troubleshoot further!
