noticing an irritating icloud backup issue on my 2017 12.9" ipad pro. As in, the only time it performs one is if manually done. Then it takes over an hour, which may be an additional issue. Here are the stats: 12.9" 256gb gen 2 with 12.2gb used 50gb icloud storage w/5gb used 304 photos, no videos I am used to my ipads, of the past backing icloud up as I charge overnight, usually every other night with my typical usage and taking about 3 minutes if I ever do backup manually. This 12.9" is set to allow auto icloud backup same way my other ipads have been. I am know beginning to get the message of 'icloud has not been backed up for 2 weeks'. Any help or should I call Apple?
