Huge problem with AP+

I was doing a flight between MMMX and CYUL. The flight was saved properly near MMMX and resume in background with AP+. 24 hr later, on the home screen, it shows 00h29 min left to CYUL and I see the plane near CYUL. When I resume the flight, the plane is near MMMX where I saved the flight before. Any idea whats going on ?

Device: S24+
Operating system: Android

I change the time and it works. Weird
