If you use Teapplix to manage your TEMU orders, Temu just sent out notice that all USPS and FedEx shipping labels must be purchased from Temu and not your own carrier account.
In Teapplix you can achieve this by going to our Integrations page and edit your Temu integration, check the following checkbox
[] Buy Shipping Labels from Temu
Once turned on, all your shipping labels will be purchased from Temu. Notice that some carrier options that you currently use may not be available from Temu. You may need to contact Temu on how that can be solved.
