Hello all

after a long period of time of no use of the above mentionned web site, I entered a quadratic equation yesterday to show the site to a co-worker and surprisingly I got just about nothing as a result, whereas I do remember being astonished by all it was able to offer in the past.
On the contrary, invitations to subscribe to the "Pro" version were dispatched all around the screen...
Did I miss something in the meantime? Is WA no more available as free version? Or is it "me"?
Waiting for your feedback.
Kind regards.
