Well, per the announcement page, under the “Current Known Issues” section, and related support page:
Outside Workouts
- Outside Workouts Completed on Wahoo or other device or uploaded via Strava don’t count toward Progression Levels
This info and all other aspects covered in those sections have been present there for many months. This is a beta after all, and something that is part of the process of incomplete apps/services like this. If it doesn’t work, you can turn AT off and continue to train without it until they address this or any other issues that prevent your use as desired.
