Recovery Steps for USG FLEX/ATP Series Application Patrol Signature Issue

Hi @bymusty
(1) If the newly released 1.0.0.20220316.0 signature is updated on devices that are affected by the signature and not rebooted, will the device be fixed?
-> The affected version is 1.0.0.20220310.0.  If your device signature version is 1.0.0.20220316.0. You can reboot device without upgrade to 5.21P1 firmware.

(2) If the devices before the 5.21p1 firmware (for example 5.02 - 5.10-5.20 firmware) that did not receive the signature dated March 10 before and were not affected by the problem, update the signature dated March 16, is it a problem that the device is rebooted?

-> Both of questions are the same answer. The affected version is 1.0.0.20220310.0.
If your signature version is 1.0.0.20220316.0. You can reboot device without upgrade to 5.21P1 firmware.
If your signature version is 1.0.0.20220310.0. You can upgrade to 521P1 firmware before reboot. Or follow the steps to recover your device.
