My app was rejected because of Shopify related endpoints throwing 421 error codes

I’m happy to share the full screencast with someone from Shopify - but here’s the details:

  • The reviewer could not paste into the text input (Shopify Polaris Text Input component)
  • The reviewer went to the console and moved their mouse around to show several 421 errors coming from Shopify-owned /well-known/* endpoints.
    • I do not own these endpoints! They seem to be causing issues with UI and causing some issues for the reviewer. Related image below from the screencast.

Can someone please assist me with this? The old review process let me talk with the reviewer directly but there seems to be no room any longer for nuance. Instead I must wait until June 8th to resubmit. At which this whole cycle might repeat itself again.

Thank you so much for your help!
