VTR not cahnging after valid tracking number upload

Hello,

does anyone happen to know why updating VTRs through order related files on SellerCentral doesn’t work?

I’m pretty sure trackings are valid and reflect on the order details.

However; my VTR doesn’t change even after waiting a couple of days. We were able to edit trackings through order details and never happened to have a problem.

Is there any kind of solution to this?

Thank you so much.
