I've added a date and time field to an activity ('departure date'). The problem is that it steadfastly refuses to display as anything other than YYYY-MM-DD HH-MM-SS even though the custom field is specified as d MM yy with a 12 hour time format. This is when I hit 'View' against an activity in a list of case activities and get a pop up. Which does look odd when the activity date is displayed correctly as (e.g.) 14 June, 2021 1:03pm. My 'date preferences' were all set to default (I'm in the UK) but to try and fix this this I've set the 2 activity dates formats to d MM yy, and the custome the same. But to no avail. Civi is at 5.37.2 - I guess a bug?
