Why can't I cut and paste in Android TV?

John from San Diego, CA
Android TV

Rob has an Android TV but he's having issues cutting and pasting in his email. Scooter X found an Android TV subreddit talking about this very issue here - https://www.reddit.com/r/AndroidTV/comments/6y0qrk/copy_paste_problem/. There is a weird fix in there, by installing the "hackers keyboard" in the Google Playstore. Apparently, that fixes it. Mike B also found this from Google - https://chrome.google.com/webstore/detail/office-editing-for-docs-s/gbkeegbaiigmenfmjfclcdgdpimamgkj?hl=en
