My son signed-up for Tinkercad at school. Then I signed up for a free parent account here at home. Now for the past 2-3 months, he cant sign back in. I paid the PayPal fee and all and now his username isn't recognized and only my name for the email address we both used is recognized. I've reset my password to try to access the site and I'm not even sure how successful that was. I need him to have access. He's falling behind in his class at school.
