Not really a bug but still a technical question:
I did the Zwift cycling 101 plan. During the final ramp test to establish a base FTP I made it to ~300W before blowing. At about that time the on-screen prompt said something like “congratulations If you’ve made it this far your FTP is above 250 and you should do the full FTP test.” Then when I finished the ride and returned back to the main menu I got a notice “Congratulations we’ve detected an update to your FTP to 150 and automatically updated your profile.”
So what’s my FTP 150 or 250? Should I go in and manually update the value in my profile?
