Hello, I tried to do cloud backup of my Iphone 6s plus and it says "there is not enough icloud storage available". It says same even if I UNchecked "everything" to backup (except for contacts/calendar). It also shows the Icloud storage usage is "2.1GB out of 5GB". Could anyone please advise on how can I take icloud backup? I just need basic OS and contacts to be backed up to Icloud (just in case though I take itunes backup every week). If IOS 12 alone takes more than 5GB then whats the point of free 5GB standard quota? Wondering if I can empty the icloud storage (without deleting on the phone) then try the backup? if yes, how can I empty my icloud storage space (free up that 2.1GB at cloud). Thanks!!
