Reality editor doesnt detect target

At 1st the reality editor do detect my image target. Try with the interface. It work
Then i close the app
When i reopen the app. It doesnt detect the image.
1.I try printing out new one
2. Reconnecting wifi
3. Restart my iPad
All not working

Is it me only who have this problem?

Can you try to reupload your target to the server?
It is possible that there is an issue with the verification.
