iOS 12 Bluetooth Uconnect issue

I updated my iPhone 7 to iOS 12, and immediately noticed that there is now a significant lag in song selection when connected to bluetooth in my car's Uconnect head unit. When a new song plays, the song run time is frozen for exactly 30 seconds while the song plays. If I try to toggle next/last track selection using the car's audio controls during this time, nothing happens until the 30 seconds pass, then it changes to the next song. It happens very consistently now with every new song that plays. Also, during some songs it'll do this freeze for 30 seconds where song navigation won't trigger.

Can't overstate how annoying this is. Has anyone else experienced this?

Just over a week away from iOS 13 and hopefully this national nightmare will be over soon. Can't believe we've been driving around for 12+ months dealing with this BS. Fingers crossed.

This issue seems to be fixed in iOS 13. I noticed it immediately appears for me on pretty much every other song when I play through Bluetooth. Haven’t had lag since the update.
