I don’t know what you’ve done with the seller orders page, but I can not get my script to fill tracking numbers working with it anymore. I am setting the .value of the tracking number input to the correct tracking number and it shows up on the web page, but if i then click the “shipped” button it shows “shipped (no tracking)”. I don’t know why you made this gratuitous layout change and even removed the “unshipped orders” page.
Figured it out, you have to fire the “change” event on the input using .dispatchEvent(), due to jQuery keeping shadow state of everything. To all web developers: avoid jQuery at all costs. It bloats your website for no gain.
