'This extension may no longer be supported" Should I be worried?

I was on Google extensions and this was one of the messages appeared. In full, it reads:

This extension may soon no longer be supported

Remove or replace it with similar extensions from the Chrome Web Store

What should I do?

I’ve been having the same problem with the app for a week.
I already sent 5 messages to the owners of the app.
But they are silent, even though I am a paying customer of the app.

Hi!
I have the same problem: When you go to Chrome to download the extension:

You have this note:
This extension may soon no longer be supported because it doesn’t follow best practices for Chrome extensions.

Please let us know what is happening and whether the app is going to be supported or not.

We would really appreciate this information (or who we should contact to know more).

Thank you.

Today when opening Edge, I got a notification that said “Language Reactor was blocked because it contains malware.”

The extension is now gone from the Edge store.

Should I be worried?

I’m having same problem on Edge, This extension contains malware.

Could’t using it. What can we do?

Move out of Chrome/Chromium… sadly Google is blocking a lot of apps in disguise of “privacy and security”
