Has anyone else been denied replacement 2020 airpods pro due to static and crackle?

If you bought them from a not Apple authorized third party, the purchase date was the day that vendor bought them from Apple not when you bought them from the third party.

If you think the purchase date is incorrect, click on this link to read how to update your proof of purchase --> Update your proof of purchase - Apple Support

To update your information contact Apple Support by phone. Tell the advisor that you need help with your Apple Limited Warranty or AppleCare plan expiration date.

Here’s what you need when you call:

- The device serial number

- Your sales receipt

Also realize it isn't a matter of "we cannot intervene". We couldn't even if we wanted to. The majority of responses here come from other users (like the two you have received so far) like yourself, and even those from Apple are not from people tasked with doing more than providing guidance like we do.

This is not a chat room. You can try contacting Apple again regarding the time period but I’m afraid we cannot intervene once Apple makes a decision.
