Infinite/very high max speeds
I'm using the app while cycling and the track colour is usually all red because there has been an unrealistic speed spike at some point. This spike causes the max speed to be over 1000kph or infinity. If it would help I can send an example gpx privately.
The gpx contains elements like this: gpx10:speed2.1931504306849092E-4</gpx10:speed>
version 2.5.3.b130 on Android 10
