MCS will mark the profiles in error state after 30 retry counts (max) when the profile is not being applied on probes.
In UMP USM, you have no way to reset the profile errors, so that it can retry to deploy the template again on probes. We can only reset the profile status via SQL queries in the backend.
In addition, USM does not provide the way to select more than one profiles applied on device/group.
It is definitely worth adding functions for multi selecting the profiles (check boxes) and have the reset button in addition to Save and Cancel on USM portlet.
