I have recently started having issues with CC on my iPad. I checked to make sure I didn’t need an update & I am current. What is happening is I touch the icon to open CC. It brings up the main CC page. When I click the black button to open it, it crashes. Today is the first day that I can’t get it to open at all. I have a video if you need to see what I mean. I can’t put the video here but if you respond through email, I will attach the video there. Thanks for your help.

I try to connect to Calibre via Calibre companion as wireless device. At first it seems to work, it says "Coeecting searching for Calbre", then "Connected Starting initial sync", then after a few seconds of that message, I get another message that tells me "Disconnected from Calbre" and I'm back at the beginning.
