TBT is working

I got the TBT working great yesterday.
Was it solved in 4.12 or was it my work flow?
I imported a GPX into gpsies.com. Created waypoints with TBT and other. I did put all waypoints on the course line and didn't move them. Named them with a personal name.
Exported to a GPX track to be able to preview map (bug forme eith fit files) and to get the waypoints to show up as flags.
Exported to TCX course that I then converted to FIT with McBadger tool.
I mortem both to 5x.
I followed the fit file with routing->activity set to hiking and routing to follow course.
TBT showed up from the beginning.
