Can't Disable Handwriting Mode ios10 Iphone6s
Hi, so I recently picked up a brand new iphone 6s from my phone provider and just finished setting everything up. I was aware of the handwriting feature added in ios10 as I was using it on my iphone 5 prior to upgrading. However, this is where things get confusing. Now I know how handwriting mode works and that you're supposed to be able to disable it and revert back to a regular keyboard by hitting the keyboard button in the lower right of the text window, however this has never worked for me - on my iphone 5 and even now on my brand new iphone 6s. Every time I hit the keyboard button it simply retains portrait orientation. I've tried turning the phone off and back on, I've even tried installing third party keyboards to no avail.
I'm currently in the process of backing up my iphone so that I can try wiping everything, testing landscape texting, and then restoring everything again. I'll post if anything changes but so far nothing has worked. I was curious as to whether or not anyone else has run into this problem. I haven't been able to find much info elsewhere besides a post in the community referrencing the same issue on an iphone 5s with no solution or useful info posted. Help would be immensely appreciated. Thanks.
iPhone 6s, iOS 10.2.1
