Can not sink after editing sequence

It worked for a few weeks and when I was making changes to the sequences it will no longer sync. I have tried to connect from multiply devices with no luck. I can still move the robot from the controls page and get info back from the robot. In addition I am not able to take pictures. I have rebooted the robot without any success. I Have Not “reset to factory defaults” as I don’t want to try that unless it is a last resource. Any suggestions?
