@frank-chu-viewsonic-com Is there a way to go back and select package installer. I have a few teachers who pressed the other option so any time they try to update, it just says file extension does not match.

I have many teachers getting a message each time they open the ViewBoard app, "A newer version of this application is available." So when they touch update, it reads, "File extension does not match." They are still able to use the ViewBoard, but I am wondering how to fix this issue so I will stop getting asked daily.

I am an IT director at a school district in Oklahoma. My teachers have had a ton of issues with the sound on the ChromeBoxes. I am wondering if anyone has a solution or has been experiencing the same issue? We have tried to replace HDMI cables here and there, but it has only proven to be a very temporary fix. I know that the sound control on the TV and the ChromeBox are two different controls. I have had both of them on full volume and had still no luck. Any help is appreciated! Thanks

@kpeavy-randolphboe-org We had a power surge in the buildings overnight that took out most of our ethernet ports temporarily. Our IT department restarted the switches in each building and it started working again!

@kaitlyn-peng-viewsonic-com Thank you Kaitlyn. That was the answer I was looking for!

When my teachers are using the built-in whiteboard app already on the panel, they are able to hold their hand on the board and erase with the big eraser that pops up. However, when they switch inputs to the ChromeBox, this eraser trick does not work. I have messed with it myself and have had no luck. Is this eraser trick not supported on the android version?
