Adobe flash is not updating
If Google has released an update, but not yet delivered it to your device, it will be downloaded and installed.
It is certainly a possibility that Google has not yet made available the update for Chrome's Flash plugin.
Google is usually pretty fast when it comes to Flash updates in Chrome.
But if you notice that Adobe released an update for Flash, and Google did not yet push it to your device, you may use the method to try forcing the update.
Instead, look in the address bar, then click the puzzle icon.
From here, you can choose whether you want to allow the website you are viewing to always run Adobe Flash or Allow it once.
The main reason why that is the case is that users don't have to worry about the installed version of Adobe Flash too much, as Google takes care of the updating.
While this works fine most of the time, usually before or at the time Adobe releases updates for Flash, it may happen that Google is late to the party when it comes to pushing the updated version of Flash to Chrome installations.
For example, popular websites like Major League Baseball’s and tools like Pixlr still require Flash.
Fortunately, Microsoft started bundling Adobe Flash Player in its web browser in Windows 8 and continues to do so in the latest release of Windows 10.
To change that, open the More actions menu in the top right corner of the Edge browser, scroll down, click the View advanced settings menu then toggle on Adobe Flash Player.
This may be by design; as a security measure, Microsoft is limiting the use of Flash where ever it can.
So, if you are greeted by a web page with only a puzzle symbol, don’t be puzzled.
