we have an .xlsx spreadsheet on our nextcloud to be shown permanently on an always-on display as a daily overview. For this the sheet is shared with a user which has only read-rights. He cannot change the spell correction option, so by default all words (we use only abreviations) are underlined with red. Sometimes we have to restart the computer/browser meaning, even if I disable spell correction by login in with the admin-user (write-rights) and disable the spell correction, it will return once we restart the computer/browser.
Is there a way to disable spell correction permanently? I tried to deactivate it and saved the file, this is not enough.
