Dear Pepijn,
Thank you for your help,
about the information needed,
1. When sending out the schedule with the content are the screens online on your server?
A. Yes, the screens are all online when sending content.
2. Is there any difference between the content that is accepted and not? What kind of content are you sending?
A. No, there is no difference, content types are images and videos.
3. Is there any difference between the screens that are working and not working? You can think of connection type Lite or Premium/ Model/ Firmware/ different network.
A. Again there is no difference between the screens, same model and same firmware, we have few trial premium licenses but the problem is same.
Regards,
Yousuf
