Runway 9R EGLL Glitch

Hiya. I’m in EGLL using currently a 787-10 British Airways Livery performing a flight to JNB when I taxi as normal to Runway 9R. As I line up on Runway 9R, I increase Both engines to 90% and I’m met shortly after takeoff roll, my aircraft seems to slowly fall into the ground (almost like a glitch) it then performs numerous stunts and reaches 500mph as read on the screen. Please help me as I cannot proceed to takeoff and I’m using this 1 month subscription which runs out shortly. Any help would be kindly appreciated. Thanks

Hi there this is known. Try restarting your device and if that doesn’t solve it reinstall the app.
