Birthday 1 day off in app

On my dashboard my birthday is correctly listed, but on the app (iPhone, Zwift Mobile Link v 1.4) it’s 1 day earlier. 19 instead of 20 October

Same here.

yep, same, how to fix it? If I set it in Zwift app to 17, in mobile link app it shows 16, if I change it there to 17, it start to show 18 in main app
