Assigned policies to iPads time out and fail

Question

after publishing a new policy, currently not unlocked iPads dont apply the new policy and if not unlocked within the next few days, the assign policy task fails completly. Is there a way to increase the amount of retries for assigning new policies to curently offline/locked devices? With around 75 iPads there are always a few not online for a week, currently i have to check every iPad one by one if the newest policy is active. 
 How exactly does the process of assigning new policies work, is it a pull or push configuration?

Hi Marco, 
 Thanks for reaching out to the Sophos Community Forum. 
 You can find more details on how device Syncs work in the following article. - Sophos Mobile Control sync process 
 When a policy is sent to a device, this is done in via a "push". The SMC application will need to be open in the app switcher to respond when this occurs. The following article describes " Tasks that can be processed on a locked iOS device ".
