iCloud completely stuck on uploading items
My iCloud Drive stuck on sync and I don't know how fix this. I've tried anything, moving files in and out, disable/enable iCloud services, clearing iCloud cache with stopping bird process. Now I've removed any files from my iCloud Drive from Docs and Desktop from my Mac and from iCloud on iCloud.com and tried to create some using pages and it stuck even on sync that single file.
If someone knows how to fix this thing I will be very happy, because I spent over 2 month paying for iCloud Drive that just doesn't work at all, any single file wasn't synced during that period. And I can't write to the apple support because it isn't available there.
