Approach on long haul flights with 747 failed

Since last year I have several problems on long haul flights with 787 and 747. Durring the approch the FMC or also the displays dont refresh the last Waypoints or the routing and the Autopilot doesn’t follow the planned flight path. It seems that every Navigation freezes just before landing. Also the ILS is not working at all.

Has anybody else experience with that ?
