Pardon this question, but I couldn't find anything. I have a few issues with the VNAV. I am running 1.3

Sometimes it will repeatedly Pause at TOD and then the TOD will vanish and the plane will hold cruise altitude. I will see TOD appear on the plane page for a second, the FMS will say, drag required, and then it will start to pitch down, then all that will vanish and it will go back to cruise.

There's also no regard given to any speed restrictions, 250/10000 it will wildly accelerate then indicated on the FMS, drag required.

Are these known issues? Thanks, great product otherwise, I just revert to manual flying!
