I see there are two previous posts on this but both are archived and neither have a resolution. The profile date of birth in the companion app and the game are always different by 1 day. I’m not that fussed but I’d like to know which one should be right. Zwift might want to give me a birthday present after all…
can confirm. I also noticed.
I am also happy about a present. 
Yes its an ongoing bug we’ve monitored. No eta on a fix but we’re aware of it.

Maybe Zwift will give us 2 presents?
