A. To initiate a return, go to your order history in the app and select the item you wish to return. Look for a 'Return' option and follow the prompts. If you encounter issues, ensure you have the correct return window and conditions met for the item. Check the return policy in the app for specific guidelines.

B. If the return process is still problematic, take screenshots of any error messages and document your steps. This information can be useful for troubleshooting. You can also try using the Trendyol website to initiate the return, as it may provide a different interface that works better.
