Upgraded to iOS9, search in note app; search in spotlight; business yahoo email sent items don't sync anymore with website and vice versa.
Before upgrading to iOs9:
SEARCHING IN NOTES:
Before, if I search through my notes, it brings me to the part where the word is and it even highlights the word.
SEARCHING IN SPOTLIGHT ON SOMEONE'S CONTACT:
Before, when I write a name in spotlight, it easily and shows more faster the person I am looking for from my contacts list. Now, sometimes it shows for some people. Some people I search, it doesn't
YAHOO BUSINESS MAIL:
Before, no problem at all. Now, going crazy. So, according to yahoo, delete what's present and add it through "other" option and not on the Yahoo! I did all of the steps. It did send and receive again. BUT...when i send email from phone, it doesn't show in sent items anymore in the website and vice versa. No calendar, note, syncing either. Please fix.
