Jamf self service must be associated

[alessio_tedesco]

we're having random issues for which the app jamf self service in ios is getting the below error , it doesn't happen with all the devices and even always , sometimes after an upgrade, sometimes not.

Welcome to Self Service Mobile Self Service Mobile is a component of the Casper Suite, developed by JAMF Software. This app must be associated with a JAMF Software Server. Contact your IT administrator for information.

Do you guys are having the same issues or is it just me?

I'm getting it frequently on iOS 14, enrolling via Configurator 2 (retail purchased devices). 
Devices appear enrolled, managed and supervised in JAMF. 

Odd, that app assignments via static groups is also working.
However, I need to distribute beta .ipa apps so Self Service must work.
