Yodeck is an online service. So, Internet access is required for your Player to be managed properly. There are a few caveats, though. Here, we provide all the details on what works and what doesn't.
No, it will not. Playback will continue as normal.
Playback will stop. Your Player will start showing a warning message in the bottom-right corner 3 days prior to stopping. Eventually, somewhere between 30-40 days after losing internet access, your Player will stop playback, and it will display an error message.
Not entirely. If you can visit the location once every 30 days, providing Internet access through a WiFi hotspot on your cell, you will allow the Player to retrieve the latest info, and it will continue to work fine. And for sure, you must address the clock sync issue.
Yes. Videos (including YouTube videos) and Images are downloaded locally by the Players. Only Web Pages and Live Video Streaming won't work while offline.
No. Content and scheduling updates must be done through the Internet.
