In the admin when clicking "add model +" I fill out the fields to create my item then when I click "Save and add another" or "Save and continue editing" it redirects back to the model list view even though the item was added successfully. If I click back on to the item to edit it the buttons work how they should.
I'm not sure if this is a bug with the admin. I've tried it on 2 projects now. I'm using Django 4.1.
I uploaded a sample project so you can quickly see if the issue happens for you too.
