Normally, navigating on the map usually runs at or near 60fps.
I can't measure it so I'm just eyeballing, but the fps was definitely hitting single figures today every time I used the app. It definitely never got above 15fps.
The entire time I was doing anything it was really really struggling. Everything loaded completely fine, but moving around on the map felt like being back in 2014 playing Minecraft on my £200 laptop.
