Does deep linking work for anyone? Specifically Negotiations?

Content

We are trying to get Deep Linking to negotiations to work.

Whether Negotiations (admin view) or Negotiations (supplier view), neither seems to produce the desired effect.

At most, we end up being transferred to the right page, but without the selected negotiation showing.

i.e. https://fa-POD-test-saasfaprod1.fa.ocs.oraclecloud.com/fndSetup/faces/deeplink?objType=NEGOTIATION_SUPPLIERUSER&objKey=AuctionHeaderId=300000002783248

takes us to the Active Negotiation search page with no results.

If we add &action=VIEW then we get a blank page.

We've followed every guide and Doc ID to no effect.
