Thanks @Yemi_Odeyemi - we get the notifications via Github, so please don’t post here as well. We are getting lots of notifications at the moment as we will respond as soon as we can, but expect delays and do not post the same message in multiple channels. Thank you.

Alright, thank you.
I would go ahead and suggest some additional UX improvements on the issues section while i wait for your feedback
