Thank you for your post.
If you have always updated through the iPad, then you won't have the ability to roll back to a previous version.
The change was made due to requests in the Feature Requests web form, mostly from users who had difficulty accessing the button at the bottom of the display. To enter your own suggestion to have this moved back, or provide a preference setting, go to:
The entries into this web form are monitored by Development and Product Management where each request is discussed and considered for a future release. Although I could copy your post and paste it into the web form, there are a couple of questions asked that only you can answer.
Thanks for your reply. Have now made a feature request so will wait to hear back.
