I’ve just updated to “Built-In CODE Server (AMD64) - strangely after the update the close-button (X - top right) disappeard in Nextcloud-Office-Apps. The Nextcloud Button / Symbol (top left) with which it used to be possible to go to the Dashboard now seems to point to the current Office-App itself. So now the only possibility to leave the app seems to be the browsers back button?!
@dimpflmoser By seeing the image it looks like the close button is there but somehow the color of that close button is same as background color for toolbar…
