Pour créer une vidéo, l'appli parvient à sélectionner certaines images mais d'autres sont rejetées, alors qu'elles sont toutes stockées sur mon téléphone.
When you say "rejected", do you mean you received an error message or just were not able to upload it? Can you show us a screen shot of the full browser window with the error? Can you describe (or show us) the subject of the images?
I'm sorry about the issue. Could you share a screenshot of the complete browser with the error you're getting? Can you also try using a different browser?
