Hello my concern and inquiry is about whether or not somehow my yahoo account has become the primary storage for one of my iPhone options of storing notes.**My ICloud will back up everything else but my notes, and for whatever reason it's a year behind, but when it comes to notes I see where I have a folder on my email account that says 'Notes' that has most of my notes stored. Over **** verses my ICloud account which only has ***. And I've talked with Apple support extensively and they are dumbfounded as to why a feature that should be stored by my iPhone and Icloud is instead being backed up and stored in my yahoo account in a folder. I see it in the folders section of my e-mail. I am a writer so my notes are used to write down ideas and are extremely important to me. I'm asking I guess is there anything I've done or something wrong with your product that I'm using such as my email address' that has manually taken over storage from my Icloud.**This request is time sensitive as I am waiting to upgrade my phone, but can't because I cannot get my notes to backup to my Icloud or anywhere else but my yahoo account where they show up in a folder in my email page.
