On the website if you search for a workout and select Endurance + Productive (or achievable) it actually lists Recovery workouts first. This behaviour does not appear in the App.
By ticking the Productive box, the search is being personalised based on your current Endurance PL
I did the same search on the desktop: Endurance; Sustained Power; Productive and got different results.
Note the workout count is different (10 of 57)
I haven’t got a device with the app on here to see if it gives different results to the website for me.
Thanks for letting us know! We will get on fixing this.
