I missed my 1st session, just because I'm used to 24h format, and tricky 12:30AM confused me, even though a warning was shown before booking. That made me feel stupid and I had to apologize to my mentor 😄
Would be nice to have an option to change time format on setting page. Or set 24h international format by default, because it's best and clear for any user from any country... and any level of IQ 😄
