I just registered for ZwiftPower. Unfortunately not all my races have been synchronized.
Zwiftpower won’t pull in past races, just the races you do from now going forwards.
Nono, they have synchronized past races, but not all.
That’s not how it works.
You’re lucky if it has somehow imported an older race. Maybe ZP were doing some processing of older races in an attempt to catch up with some backlog, or something like that.
