Upgrade From SMC4.0.4 to 5.1.3 - SMC App Can't Synchronize

Question

I upgraded from SMC 4.0.4 to 5.1.3 today, and now i am having an issue where some (but not all) of my users cannot synchronize the SMC iPhone App with the server. They constantly get a "synchronization Failed - Authentication Error". A data refresh from the server will not refresh the App Sync either, but it is still successful. I can still control the phone (lock it, etc) from the server, but just can't sync the app from the phone. Anybody else experience this? Any help greatly appreciated.

Hi, 
 
indeed an old activation token seems to have been the problem. However, In my case only the following order of steps was succesfully: 
 
- remove the control app from the device 
- install the app again (I've pushed the install from SMC and I've done a restart before) 
- sent out the "Reconfigure SMC app" email (not to the device, cause it is not compliant and can't receive any mails. The User received the mail on his notebook) 
- scan the QR-code that comes with the mail 
 
Now all devices can sync the app again! 
 
Thanks for your help.
