VFR Map not working at 75 degrees north

VFR map stopped working at aroung 75 degrees north.
I am flying from ENTC to ENSB (Svalbard Airport) which is located around a latitude of 78 degrees north.
Around 75 degrees north the VFR map stopped working and it does not scroll anymore up.
Same issue with every flight ? Is this a known bug ? How to solve this ?

Best wishes
