It only took me about 5 years 
The advice on here helped quite a bit. But, looking at a lot of footage and paying attention to some things, I came to the conclusion that I was shifting the sail and stepping too early.
Today was spotty and a bit choppy, but I managed to run the old JP Xcite 120 with an 8.0 when the tide was too little to foil.
I did some drills at first, which wast just me carving through the jibe without shifting the sail or my feet at all to feel where the wind flipped and to get more used to it.
After some of those, and a few tries, I finally got one out of 4 real attempts. After that the wind crapped out.
But, I focused on really sheeting in and carving with my old rear foot pretty forward, bent knees, and got my front foot in the strap but heel was way up and lifting hard. I knew I was past downwind, stepped, flipped, and bam I was still planing and got in the new straps!
Now that I have that feeling hopefully I can replicate it on a day where there are less dark clouds and rain spoiling things.
Superb!
You can try now first the sail flip and than the step...
When flip, hold the top of the mast somewhat inside turn (tilted like the board).
Adding to the chorus. Well done! I've known people who windsurfed for decades who never pulled one off.
Welcome to the endless merry-go-round Well, the fin version as you're already on the foil version. 
Well done ! I've been windsurfing (on and off ) for a long time and still not planning out . I have on a lucky few. This is my mission for this summer !
