The App description starts with an important note:
For CRM 2015, this app is supported on iOS 6, 7, and 8. For CRM 2013, it is supported on iOS 6 and 7.
My iPad is still on iOS 7 so I am not able to test this incompatibility.
The Changelog is the following:
- Use multiple dashboards on the go
- Personalize your Home page
- Create records and capture notes while disconnected
- Support for additional languages
- Bug fixes
