Lots of channels missing after installed mini box

I'm in the same boat. I've tried running the channel scan a few times and I am still missing almost all of my channels.

I have an update. I called into customer service and they told me that the work order was not set to go through until May 13th, but since I was calling they were able to push the signal through and I now have full access to all of my channels. I hope this helps you!!
