Unable to install app via OTA on MDM (ios11.2.6)

We have enterprise app and we send updates of app via itms protocal that OTA uses.


I have two iPad device one is running ios 11.2.6 and other has 10.3.3

Both device configured with MDM having app installation restriction enabled

When I try to install app via OTA on 10.3.3 its working,

but when I try with 11.2.6 nothings happens, installation not working.


Is that OS bug or something that we need to configure on device that running ios 11.2.6 ?
