Yep. I had to enable LT plugin back and to restart the browser to make it work in the input form of this forum.
So, the main problem is the conflict with Grammarly.
Is it possible to add an option to select any text and check it with LT via plugin? May be, without being able to correct errors in text, however, at least a convenient way to list them. There is always an option to copy text to LT website and check it this way, however, this leads to a lot of additional actions.
I have still an issue with language auto-detection.
Sometimes with short texts or multilingual texts the auto-detection feature overwrites the language selected by the user. This is a bit annoying. I think the users must be allowed to choose the language they want at any time.
Please check the version you have. If it’s not 2.0.7 yet, please try 2.0.7 (by uninstalling and re-installing - or just wait 1-2 days for the full release).
New plugin does not take into account the visibility of the text layer. See a set of screenshots to present the problem from google inbox web interface.
Looks OK:
