Bug: Alerts not marked as read
When I log into Duolingo I am on for example on German language skill screen. I see I have alerts to read. I open them and then they are marked as read. I switch to other language (e.g. Spanish) and I see one more time that the same alerts are marked still to read. So I open alerts cloud and then they are marked as read. I switch back to German .. alerts are still shown as unread.
I can switch in this way many many times :)
