I can't get past a simple challenge because I can't uploade a profile picture. I wonder if the user role or somehtings is corrupted. 
https://trailhead.salesforce.com/modules/chatter/units/chatter_intro
I select upload, browse, choose a jpg, I am able to crop it, then save.
I am expecting it to save and appear in my profile. But it never gets saved and does not appear. 
 

trying to finish the admin beginner trail, but in the module 'Lightning Experience Reports & Dashboards' and then 4.) 'Visualize Your Data with the Lightning Dashboard Builder' 

I've done everything that is asked but it doesn't want to clear and I get the error:

"Challenge Not yet complete... here's what's wrong: 
Could not find a component in the 'Big Deals' dashboard with the title 'Opportunity Stages'."

This is a pretty straightforward exercise, so yes I'm in my personal dev org, and yes I have a Big Deals dashboard with the right 'Opportunity Stages' component (right name, donut chart, everything just how it should be,

any ideas on how to clear this trail?
