Why do some challenges not appear in the companion app on iOS and some so ? Eg Etape challenge and Climb of the week are not showing in companion so cannot be added to my plan
There was a setup problem with the E’tape events this week vs the climb portal, and they were removed until the problem could be fixed after the weekend.
If you’re talking about the on-demand rides on climb of the week or L’Etape events, those are not (yet?) supported by the Plan feature. More discussion about that over here: Introducing Planning in Zwift Companion (Replacing “My List”) - #51 by Mike_Rowe1
