Thank you for trying it out! Currently, the event block simply displays whatever is entered into it.
The “Where” field is just plain text. You should be able to type freely after clicking on the placeholder text or tabbing into the field. I noticed that the cursor doesn’t show up after clicking on it in my browser—however, I was still able to type. If that’s the issue that you’re having, I can log the issue in the Gutenberg plugin since that’s where it would need to be fixed.
The “When” field was intentionally left without a time zone to keep the plugin simple to use. The time entered will be the time displayed—no timezone is listed, so the assumption when reading it would be that the time zone would be based off of the location entered in the “Where” field. I realize that this can be confusing, for example, when you’re running an online event where people from multiple time zones would be attending. So I’d suggest, until the location and time can be improved in the plugin, to add relevant timezone information in the “Where” field or in the description.
I can’t say when this feature will be worked on at this time, but hearing feedback like this helps us know which things are more important to users, so I appreciate the time spent trying it out and letting us know. ??
