Hi everyone,
just in case some of you wonder what is the status of this request:
TAC has opened back the ticket and has investigated the behavior (Thx rgin). So, I had an update today from TAC, basically it would not be "fixed" in Airwave but on the controller. From my understanding, the controller dev team will make a change in the way the AppRF ACL are handled by allowing us to delete those ACLs. There are no ETA for this modification.
That will definitly fix the issue (from my standpoint). Will see what is the result.
Thx rgin for your help on this one!
