Removed 'Auto SMS' feature. After this update, at set date and time user's default Messaging app is opened up with pre-populated details and user has to send sms himself/herself.
Recently there has been an update to Google Policy, which says Google will only allow an app that has been selected as a user's default app for text messages to be able to send SMS.
As our app is not a full-fledged messaging application, we have to remove 'Auto SMS' feature to be complied with Google's policy.
