Hello,   I, like many others, have been having issues with the plane not being able to follow the GS. I noticed one of the last times I flew an ILS that everything was fine until I selected flaps 45 so I decided to do a little troubleshooting. I tried an approach where I stayed at flaps 30 and it flew the GS all the way down to about 400ft BUT the plane was slowly diverging from the GS such that by the time I was at 400 the GS was off the scale (the plane was below the GS).
