Hello @denezroazhon

Please specify how did you install the app on your Chromebook device. If possible, please record a video with on-screen keyboard that demonstrates the behavior to share.

Thank you very much Constantine. Sorry for this late response. I have installed OnlyOffice through the Playstore. Here is a video capture of the problem. When I type, nothing appears in the document.

Unfortunately, this requires authentication, I cannot access the video. Is it possible to share auth-less access or upload the video to any other cloud storage?

Here it IS : https://youtu.be/qxE1YWEMOLY

Thanks. On the initial screenshot I can see buttons to minimize, expand and close the window – are these available on your tablet? The video does not demonstrate them, but I am curious why they are there.

The buttons appear when the hardware keyboard is attached, and do not when it is detached and the virtual keyboard is used.
