Looks like you're trying to open a Note Rush Level Card, but Note Rush isn't installed, or there's some other problem.
Note Rush not installed yet?
Purchase using one of the following links:
Also Amazon Appstore
Once you have Note Rush installed, try opening the Level Card link again.
Troubleshooting
If you already have Note Rush installed and are still seeing this message, there are a few things you can try:
- If you are using Safari, try scrolling up this page to see if an "OPEN" button is revealed.
- If you opened this link from Facebook (or certain other apps) you may need to tap the three-dots menu button (usually at the top or bottom right) and then tap "Open in Safari".
- iPhone/iPad: Note Rush links will only work on iOS 9 or higher. If you are on an older version you must upgrade to use use Note Rush links.
- Occasionally app links fail to initialize when the app is first installed due to limitations in iOS. You may need to uninstall and reinstall to trigger link setup again.
- Still not working? Please let me know. :(
