Volume ducking issue

I have an XR and I recently updated to IOS 13.4 and ever since, every time I receive a notification, the volume drops on my music and doesn’t come back up until I pull down the drop menu from the top right of my screen. It also doesn’t give me a sound when I get a notification while wearing my headphones. It used to ding when I got a text wearing headphones but now it doesn’t. How can I fix the volume docking issue? I’ve googled it and found an article on this site saying to fix it you need to download the latest software but that doesn’t help me because it didn’t start until I downloaded the latest software. Please help!!
