We’re currently experiencing an issue in the Grammarly Editor at https://app.grammarly.com within Chrome. The dark mode setting on both Windows and Mac may cause your screen to turn black, either fully or partially:
Be assured that our developers are aware of this issue and are investigating our compatibility with dark mode in Chrome.
In the meantime, we suggest that you turn off dark mode and restart your browser. If the issue persists, please switch to any other supported browser (Safari, Microsoft Edge, or Firefox) while we work on a fix.
