I'm having issues with iCloud on both my phone and macbook pro. My iCloud hasn't been backed up in a while on my iPhone 6. I've been trying to back it up all day because I want to get an S tomorrow. I haven't been able to back it up and have tried several troubleshooting steps that I have found. It seems the best way to fix the issue is by deleting the most recent backup. I can't do this from my phone (common problem from my research) so I need to do it from another mac device. I'm logged on to iCloud from my Macbook Pro but I can't manage iCloud. (see pic below) The buttons are inactive. What am I missing?
