Datetime Hub Variable Invalid Date

Hello,
When I try to change a Datetime variable anywhere other then in the Hub Variables page. I get an error stating invalid date. Rule machine is capable of changing the date, but I can't change it in dashboards or on the device page.
Is this a known bug? Is there a fix in the works?

Check out this thread and see if you have the same issue. In my case I just needed to clear the cache on my browser.

I read through that thread. It doesn't seem to make a difference if I use a PC with a browser or the mobile app. To that end, I did try clearing my browser cache.
