Q: Cant find auto renewal option in manage subscriptions tab !! Help Iuse iphone 6 and ios 9.2 latest

Hi Neovarun,

To make sure we are on the same page, when managing your Appel Music Membership, you don't see the option to turn off the automatically renewal. Double check the steps outlined below to make sure that you haven't missed anything. 
 

On your iPhone, iPad, or iPod touch

1. In the Music app, tap your profile icon in the upper-left corner.
2. Tap View Apple ID. You might be asked to sign in.
3. Under Subscriptions, tap Manage. If you have more than one subscription, tap Your Membership (Apple Music Membership) to see your membership options.
   
4. Under Renewal Options, choose the type of membership that you want. Confirm your selection, then tap Done.
   
5. Tap Done to return to your Account screen, and then tap Done to return to the app.

If you don't see it here, try to manage the membership in iTunes. The link above will have those steps as well. 

Have a good day
