I don’t know how it is for other non-US locales, but as a UK based user, it would be much nicer is the date shown in screenshots was in the correct DD/MMM/YYYY format. That or use the full date, eg. 11th March 2020.
It’s been discussed many times before, all the way back to 2014 apparently

I don’t see why Zwift can’t pick up locale information from the system.
