The latest iOS release is affecting syncing on select Blaze trackers. On your mobile device go to Settings > About. If the Version is 10.1.1 or below, you're not affected by this issue and it's likely your syncing difficulty is caused by a missing requirement or other common issue. Follow the instructions in Why won't my tracker sync?
If the Version is 10.2 or greater, update your Blaze to the latest firmware version (17.8.401.3) to resolve the issue. For step-by-step instructions, see How do I update my tracker?
