I'm trying out different settings and the changes I made have disappeared
Problem: If you are simultaneously configuring the InPost Lockers app and checking the shipping method selection page, the settings you entered into the app may disappear.
Cause: This occurs because Shopify saves the suggested shipping methods for a given cart for a period of 5 to 15 minutes
Solution: Move back one step to the shipping address form and enter a small change, i.e. add a character to your name, then proceed. The new fees will be downloaded.
