I assume you mean this delightful red banner that I have also received in last few days.
Still pondering what, if anything, to do (or worry) about it.
ZD has worked flawlessly for 5yrs.
No more firmware upgrades as ZD EOL with 7363 APs also EOL and f/w limited to 9.10.2
End of lifetime hardware warranty. Pity.
So not sure what "active support" will gain me. Hmm.
Sorry - slightly off topic.
