First off welafever, what is the point of your reply? Are you offering help or trying to gain points and level up? Your response is worthless to the community. When I cannot download an app or use my camera because there is "no more space" and the phone actually has 170GB of space...that's not an expectation of "flawless" that is an expectation that my coffee machine makes coffee, my microwave heats water, my TV plays what I want it to play. Geez. Do me a favor and save your ***** comments for someone else.
For the rest of you, I found that my phone had not had a successful backup in several months. It took a couple of failed attempts on my mac before I finally got a current back up, and it took a long time. Once the backup was complete the issue seems to have resolved itself. I have my phone set to wireless backup and with 256 GB and cloud storage, I seldom hard wire the phone to the mac for syncing. If you are having this issue, give this a try.
