Amazon seller central site stop working editing a item in my inventory.

iPad 6th Generation running 15.4.1. I use my Apple IPad with Amazon seller central. In my inventory of items when I hit the edit button to edit a item the page comes up blank. It comes up blank using Safari Chrome and Firefox and also Amazon App with the IPad. It does work on my computer running windows. I’ve tried this on 2 different iPads. Any suggestions what could be wrong?
