For a while now many people have complained about how slow the upload speeds are for iCloud compared to Google Drive, dropbox, and other cloud related services.
This is my second time trying to use iCloud Drive and iCloud Photos. It is literally unusable. Hit or miss. I’m trying to upload all my photos to iCloud however, it just does not want to upload.
Google Drive is much easier. May you resolve this issue? Take it to the tech people at Apple. Seriously. I would love to switch iCloud. Take my money. However the upload speeds are very bad. I’m not the only one. Google search “iCloud stuck at 1%”.
You’ll run into Apple users from years ago about this. Fix the issue. Asap. I’m sure it’s possible.
