Unable to Upload Images to Marketplace App - Persistent Upload Failures

Hello Zoom Community,

I'm attempting to submit my app "Mintstac Meeting Intelligence" to the Zoom App Marketplace, but I'm experiencing persistent image upload failures.

**Issue:**
- Cannot upload App Icon (160x160px)
- Cannot upload Cover Image (1824x176px)
- Cannot upload App Gallery images
- Error message: "Upload failed, please try again later"

**What I've tried:**
- Multiple browsers (Chrome, Safari, Firefox)
- Clearing cache and cookies
- Different image formats (PNG and JPEG)
- Various file sizes (from 4KB to 154KB)
- All images meet Zoom's specifications exactly

**App Details:**
- App Name: Mintstac Meeting Intelligence
- Client ID: JuB6Y7XeRbi5L7F6...
- App Type: OAuth User-managed app
- Status: Ready for submission except for image uploads

The error occurs consistently across all image upload fields. All other aspects of my app submission are complete.

Has anyone else experienced this issue? Is there a known workaround or does this require Zoom support intervention?

Any help would be greatly appreciated!

Thanks,
Scott
