Hi arnaudc, As per the issue description mentioned above, you are getting above mentioned message when trying to open a form using acrobat reader on android, is that correct? Make sure you are using acrobat reader app to view form, not a web browser. You can download the form on the device, locate the form and open it using acrobat reader and check if that works. Also, if its a xfa form, iOS, Android, and Blackberry mobile devices and smartphones do not support the Adobe Reader plug-in with XFA forms. Refer this help document for more info:Display issues for XFA-based PDF forms and policy-protected documents Let us know if you need any help. Shivam
