Adobe Flash has officially discontinued the program and advised Adobe Flash users to remove Flash from the computer on every user.
Requests for the removal of the Adobe Flash program have started January 1, 2021. And Adobe has blocked all Flash features so that they no longer work in Flash Player.
This is done by Adobe to help protect users of Flash Player systems and Adobe always sends reminder messages to immediately remove Flash Player from their systems.
This message is sent to inform users that Adobe will no longer publish Flash Player updates or Security Patches after the EOL date.
And this is to alert people and be aware if any Flash update notification pops up in the future and it's dangerous and should avoid it because it's not a Flash update.
