Dynamic intake form dropping file upload payloads on mobile web view
Summary: davej-53 is experiencing issues with an external web intake portal when attempting to upload multiple photo files from mobile browsers. The dynamic intake form intermittently drops session tokens during POST requests, causing the form to reset without a validation error. They've taken steps to compress images and confirm desktop success, but the issue persists due to SSL handshake resets on mobile networks. They seek technical suggestions or solutions from sellers or developers experienced with handling multi-part POST payloads in dynamic web forms.
Hello eBay Community,
We are setting up a streamlined workflow to handle high-volume damaged item proof and shipping claim documentation through an external web intake portal (hdclaims.co.uk).
Issue Description:
When sellers attempt to upload multi-file photo evidence (JPEG/PNG) of damaged postal packages directly from mobile browsers, the dynamic intake form intermittently drops session tokens during POST requests over mobile data networks. The form resets without returning a validation error response.
Technical Setup:
Platform Component: Dynamic HTML5 Web Intake Form
Target Domain: (
hdclaims.co.uk)Network: UK Cellular Data / Standard Broadband
Browsers Affected: Mobile Chrome 125, Mobile Safari (iOS 17)
Steps Taken:
Configured client-side Canvas auto-compression to reduce image file sizes below 2MB prior to POST dispatch.
Verified that desktop web browsers complete multi-file uploads cleanly within 300ms.
Inspected browser network logs; SSL handshake resets when mobile devices switch IP addresses during dynamic step transitions.
Has anyone integrating external seller tools or claim documentation forms found a persistent retry script for dynamic .co.uk web forms handling multi-part POST payloads?
Any technical suggestions from sellers or platform developers would be greatly appreciated!
