New Drivr app update acting glitchy on my iPhone 12.

Not sure if its just me and my phone, but I've noticed since the last update, that after 4 or 5 hours of running the app and navigating, my phone (iPhone 12) starts heating up and the navigation dispayed in CarPlay slows waydown and even completely fails at times.

Is anyone else noticing this or is it just something glitching specific to my phone (perhaps internal memory being jacked or a memory leak) - a newly refurbished iphone 12 that I bought specifically to run the most currrent OS which will be required in about 2 weeks.

It was working splenedidly for for about three weeks, then I noteced the upgrade, with the new pinkish graphics and now it's getting to be painful to use.
