Greg,
Sorry you’re not able to get the video to play. I even double-checked it worked with a few support team members before replying. Regardless, I am experiencing the same behavior as you when I start with the cursor on the Start Date & Time field. I’m not exactly sure whether this is a bug or not, but I’ll go ahead and log it as such for the developers to review and make the appropriate decision.
I don’t have a workaround for you in the mean time and hopefully it’s not something causing too many problems for you. I’ll also include the note about the compound adjective. I’m particular about those things as well.
Thank you for working with me on the matter and please keep your eyes on your WordPress admin dashboard and our Release Notes for maintenance release info. Cheers!
