Lightroom CC Importing Photos

Hi.

ive been having issues with the Lightroom CC since I downloaded it. It will not let me upload any of my photos and when I first open it, all it does is have a spinning blue wheel that never goes away. Mainly, I’m trying to get my presets from the desktop Lightroom CC to my mobile Lightroom on my iPad because i will no longer being using my Macbook to edit picrures (it’s old and is too slow to do anything). But i can’t tell if my presets are loaded into the desktop version because it won’t let me see/edit any pictures!! I’ve tried uninstalling it and reinstalling but that didn’t change anything either. I really need to edit my photos, and I don’t know what else to do. Can someone help me PLEASEEEEEEEE
