Thank you for reaching out. I'm sorry to hear that your iOS app is not showing a Stop Button. Our latest version is 2.6.1 which was released 4 days ago. This release has fixed the Stop Button from not showing up. Could you check your app and make sure it's 2.6.1, and that you have also restarted your iOS device recently? This will help the app refresh as well. If you're still experiencing issues, could you please send a note to our support team at email@example.com including screenshots of your version and your stop button not populating?
