I am in the exact boat! My airpods that I brought directly from Apple less than a week ago worked fine for 2-3 days max. Then one day they just stopped pairing (reset and forgot from the device 5000 times). I got onto apple and they offered to replace both left and right airpod's. I got my replacement today and the same issue persists!!!!! I am beyond furious! I rang support earlier today. He explained to me that the issue is that the Firmware is not matching up with both airpods my left one has the 2d3 firmware.... He told me that he will place a 'update' on my airpods and to let them charge for 30 mins. I left them for charge beside my phone for 45 mins! I then reset the pairing and tried... Same issue! Not to mention I had to pay €150 charge to get these brand new airpods replaced which will then be 'released back into my bank account once i return my faulty ones within 10 days' I hope they understand there may be a delay with post due to the world pandemic!!! absolutely shocking!!! I would rather buy 10£ ones from china that would probably work flawlessly than give this Trillion dollar company any more of my hard earned money! shocking!
That being said I did use to work for Google Nest as a support agent. Anytime anything like this would happen with any sort of software issues/updates the engineers would be right on it and either update the product or else replace the products with the correct software. So fingers cross this happens for us Army of 2D3 victims!!!
