Not to resurrect an old post, but for those who followed the above but also defer to the tutorial and are still getting stuck:
Disregard your instructor's instructions when told to TMS-UP to set Point/Area. Face your craft's heading toward the target then hit TMS-UP. Why isn't A/P released or you're advised you may need to turn to target? It's dissonant with the prior tutorials where any time you needed to operate your craft's controls you are released from A/P -- that is likely precisely why some get stuck there.
I double-checked that the WP was set as my SPI on the TAD; tadpole and all, turning to target was what got me to the next step.
