Reality cloud

Having lots of trouble with a creality cloud . It only seems to work when it wants to. Sometimes it’s a slicer, sometimes it’s the camera. Sometimes it won’t let me use it at all. Does anyone have an idea of how to fix this? Is it them or is it me?. I’m new to this, but I’ve printed out a lot of stuff ,from the public pages. It seems to be a lot of fun, but can be frustrating. When the cloud doesn’t want to work, can someone help me? Thank you.
