We just completed an ISE 3.0 upgrade from 2.7. The GUI seems very responsive. We cannot edit endpoints. It is almost like they are not getting loaded because the MAC address does not get populated when you click edit. We tried to import one MAC address and it did not complete. Same user tried to import another MAC address and ISE responded that a user could only have 1 import running at a time.
Has anybody experienced a similar issue?
