I found the following bug:
If you link two tables with a column which contains datetime (type date with hours and minutes) and then build a “webform” where users can select from a value from this datetime column, the displayed format does not change. It is always the format in the screenshot, which is very user unfriendly. The set format is ignored.
If you use the webapp to build the form the format is displayed correctly like it is set in the column settings.
