Two-In One Accessory Not Working After Update

I use this accessory on my iPhone that allowed me to use both my charger and the new pairs of earbuds that Apple put out without having any issue. However, after the update before the most recent, I started getting a message saying that “This Accessory Is Not Supported”, though I was still actually able to use it without any issue. Unfortunately, after the most recent update, it’s stopped working entirely. It still works on other phones though, so I’m unsure as to why this would be the case. Does anybody have an answer?
