Using Modem FW 1.3.6. Using NCS 2.6.0.
We're experiencing an issue in a test setup where we are getting this error reported (528) when trying to clear/set root certificates via modem_key_mgmt_delete() / modem_key_mgmt_write().
We haven't yet found any documentation around this error, and what this implies.
If this is error is raised, is there any way to clear it?
