Uploaded my photos from my phone, then iCloud started having connectivity issues. Troubleshooting recommended signing out and back in to iCloud. Upon signing back in, iCloud wants to sync duplicates of all my photos, and there isn't enough space and so I no longer have iCloud access. Now new photos taken on my phone won't get added to iCloud. And new photos added to iCloud from other devices won't show up on my phone. Essentially iCloud is creating a useless mess.
