is play.unity broken?

Trying to use play.unity to post results from missions at learn.unity so they can be submitted. No Go. play.unity.com keeps falling over. cant even see a page let alone upload a webGL. Hoping to shed some light on this cos the missions get stuck on a loop if you can't expletive submit proof of work. Slightly frustrating, hoping someone can see the impact is having on the learning proccess and sort it. ie uploading post direct to learn.unity seems like a natural work flow. Back to the Q 1. Is play.unity disolving with connect? 2. How do I submit work done at learn.unity? 3. Is it possible for learn.unity to accept an external url for submissions? 4. Is it possible to submit pdf's for documents, if not why do the missions ask for them? It's just a bit confusing in an otherwise smooth operation.

Thankyou p.s. I've been really enjoying learn.unity and hope to get the most from the ride
