Does she have a lot of videos, messages and files saved? Is she backing up apps? She may need to manage her storage better.

there are steps in this link that may help.

I've found with some storage it takes at least 24 hours to get updated numbers, thinking they only measure it once daily???

I'm a little confused. You purchase iCloud storage by the plan, depending on how much storage you require. You get 5GB for free, then 50GB for $.99 per month. Or 200GB or 2TB ($2.99 or 9.99/mo). I have a couple thousand photos (3k?, 4k?) on my phone with iCloud back-up and the 50GB plan is more than adequate for my needs.....I've only used 19.3GB. The 200GB plan is more of a multiple user/family deal (unless a very heavy user) and in most cases, overkill.

We kept teetering at the edge with 200GB family plan due to my daughter’s photo/video habits, so rather than fight that I sprang for the 2TB. If that’s not enough, we’ve got issues!

Also: has she gone online and deleted photos? And emptied the deleted files ONLINE?

Has she called apple support ?

Try using Dropbox for storage instead.

@bored_housewife, I also export them and save on a hard drive. I have encouraged her to do that. She told me she had gone online to iCloud and tried to delete, but that iCloud won't allow her to delete them. Also, she advises she has attempted to send the photos from iCloud to her laptop and iCloud, once again, won't let her. I have also encouraged her to contact Apple Support.

@Lars, my Dropbox fills up quicker than iCloud, I am always having to delete documents. Refuse to pay them money for more space. Will ask granddaughter if she has tried Dropbox, but it iCloud won't let her delete or forward photos, don't think it would let her forward to Dropbox.

This is a real puzzle to me. I do think she really needs to contact Apple.

I think I pay Dropbox $100 a year for 2 Terrabytes of storage, and I do this because I want to be able to access my files on four different devices. Three is the limit they will allow for free, but I do also like the extra storage that I get by paying them.

I go back and forth between L.A. and Palm Springs every month, and Dropbox makes it easy for me to access certain files at both locations. I would not mind switching, but I have had no issues with Dropbox, other than the $100 per year, which seems reasonable to me. It is also easy to delete files from Dropbox, but I have not used half of my storage yet.

Some years ago, when my kids were younger and data plans were more expensive, I had a shared data amount for our group family plan that I thought was reasonable. One of my kids consistently used more data than others and when reminded how to easily limit use, said he was "too busy" to remember to switch the phone to Wifi when possible (like when home). When this kid's data usage pushed us over the monthly limit and occasioned a supplemental charge, I sent a copy of the bill and said I was due a $25 reimbursement. WELL, that wasn't "fair". I agreed and said indeed, it wasn't fair for me to have to pay the added charge because he was lazy. That was the last time he caused a data overage.

I'd say about the same to a kid who persists in taking a lot of photos but is too busy to delete the unnecessary ones and/or is unwilling to save them using a less expensive way. They can do as they wish, the cost would be theirs to pay.
