Appspace stuck on loading card screen

Hello ​@ymp, I’ll reach out directly for a bit more information!

Hi Jay, as issues were constant we swapped chromebox with spare device just to see if it's hardware issue.
To give you additional info about the issue.
Device name: SEL-CEN-L20-Menu Board
Location: APAC, Seoul Centropolis

FYR New device is named SEL-CEN TEMP using the same channel as before.

Updates: Even though we swapped the device same issue is happening again but at least content is loaded few seconds later

 I have seen that issue and I usually have to re-register the device to fix it.  I have brightsign players however, so not exactly the same. But it is easy to do remotely through the brightsign player dashboard.  But  because you have to wipe the SD card and reinstall the setup files - it is most likely the wiping of the current files and a refresh that fixes it.  

Hi Trish, the thing is that I’ve registered existing channel to new (erased) device so it’s new a new device.

Does the channel play properly on other devices? In our environment we assign channels to devices and when we set up a device for the first time we assign a basic channel (one slide) so it sets up fast and then we assign the proper channel after registration.  I would try setting up the device with a single jpeg image channel to make sure it’s not the channel and rule out it is the device. 

There's something odd about the current channel. The publish tab lists three devices, but we've only connected one. I'm not sure how to remove the two extra devices, as they don't appear on the list.

Create a single image channel and assign to the device and if that plays.  Recreate the suspect channel and try to assign it again.
