Why is my iCloud being weird?

Hi, my iCloud account is being super weird and I don't know why or how it started. First thing I noticed was that the name on my iCloud account randomly changed to my wife's name. Neither of us have any idea how that happened. Then her phone somehow started using my iCloud account to sign into iMessage on her iPhone. Then it wouldn't let us use iMessage to contact each other. I can iMessage other people and so can she, we just can't iMessage each other. And the latest thing is that I can no longer access my mail through iCloud on safari. And the mail application on my MacBook won't let me download any attachments. Any idea how this happened or how to fix it?

You need to check the settings on all devices and find any that are identical on both yours and hers. Are you sharing the same Apple ID or email address?

  • Why would shared album reappear after being deleted from device.iCloud? If I accepted a shared album from another device onto my iphone, deleted it, but it showed up a year later, how could that happen? Share album is through iCloud
  • Is it weird that I was born in 1996 and I can't relate to being Generation Z? I was born in 1996 and I can't relate to those born after 1999 because I wasn't as spoiled as those born in the 2000s. I'm aware that there was internet in the mid to late 90s but the internet was not really used as much until say 2000. Like a good example is that a 5 year old today is on an IPhone at age 5 when they should be enjoying their childhood. I guess I call us 1996-1999 babies as hybrids while those born after 1999 are true Gen Z
  • IPhone storage is being weird? When I go into my settings, it says that I have 174 GB available on iCloud. But when I try to download something on my iPhone, it says that I don't have enough available storage. Why is it doing this and how do I fix the problem so that I can download stuff again?
  • IPhone being weird, how to reset? Yesterday I wanted to update my iPhone so I did it without connecting it to iTunes. Since then it has been showing the Apple logo in front of a black background, then the screen goes completely black and just repeats. I tried to hold down the home and power but nothing happened. When I try to connect it to my laptop it doesn't show up in iTunes. Does anyone know what I should do? I have all my stuff backed up so I'm willing to reset it to factory settings.
