Hello Yves,
I seems to have a new problem with PayPal. At the end of the registration for the payment with PayPal I ma redirected to this link : https://www.paypal.com/webapps/shoppingcart/error?flowlogging_id=e2b0d91a405c8&code=BAD_INPUT_ERROR.
Could you try to registered to see the problem : https://formationapio.com/fr/toutes-les-formations/au-canada/event/0/185-webinaire-france/175-le-ipad-comme-outil-compensatoire-des-troubles-d-apprentissage-de-la-dyslexie-et-de-la-dysorthographie
Thank you,
Pascal
