Ringer volume keeps going to full
I use my Airpods a lot for making calls on WhatsApp. But when I hang up and remove airpods from my ears, the phone’s ringer volume goes to full. It happens everytime both after audio and/or video call on WhatsApp. I thought it was a problem with WhatsApp, but recently I started making calls on Google Duo on my new iPad Air 4 using the same airpods, and once I hung up there, the same thing happened to the iPad, and its ringer volume went to full as well. Seems like a bug in iOS?
iPhone 12 Pro, iOS 14
