On your site the notification (toast) examples are not working. I tried with Chrome and Firefox and tried via company network and my own phone (to exclude possible firewall mishaps). Yesterday at home it worked and I was able to see the examples, but today here no longer works. The only thing I noticed that qa manager complaining not having permission, but no other error show. My colleagues checked on their own machines (they use Windows 10) with the same result.
