I have a Nextcloud 19-Installation with an integrated Collabora CODE-Server. The display is ok with all browsers except Safari and everything works as expected.
Under Safari (latest version with Big Sur), however, the icons in the button bar (bold, italic etc.) are not displayed. The buttons are there and have their function, but no symbol is displayed, so the use is “flight blind”.
The same thing happens with the IOS apps on the iphone or ipad (also the latest versions).
Is this a known problem? Or is there a setting somewhere that I overlooked (possibly server-side, as it shows up on different devices, since it appears on different devices)
