Stephen,
Take a close look at the GigEasy Universal holder. I have used them now for 3 years and they are great. It will hold my Ipad Pro with no problems at all.

Tried to access the web site and got this message:

I have been getting a similar error for some time from that site. Opening and closing the browser does not help.
