By the way, after talking to awesome Live Support, they've provided me SignageController, which solved issues with schedule. I was thinking that something was broken with a schedule, while it seems to be working now

Thanks a lot to Live Support technician

While I have an issue with deployment. 3rd party sticks are not rooted and I need to setup Android manually one by one (setup google account, install signageplayer, enter credentials). There are 200 pieces needs to be set up and it takes a long time to finish them all. Anyone could offer some solution? All 200 Android sticks are identical (MK809).
