I'm sorry to hear that you're having trouble with the "Arial Black" font family on your iPad. I found a post on Stack Overflow that might be helpful. It suggests that the issue might be related to the font type. Another post on Microsoft Support recommends checking the installed versions of the font and making sure that the latest version is active. If you have a single version of the font, check the font type. If the font type is displayed as “PostScript-Type1”, it is recommended to upgrade it to a newer "OpenType" version of the font. I hope this helps! Let me know if you have any other questions.

This seems to be an issue specific to iPad and Excel. However, in general, if a font family is not working as expected, it could be due to several reasons such as: - The font may not be installed on the device or system. - The font may not be supported by the browser or application being used. - There may be a typo or error in the CSS styling or font name. In this particular case, since the font shows up correctly in the element inspection, it is possible that the issue could be related to caching or the way the font is being loaded. It may be worth checking if there are any conflicting CSS styles that could be overriding the font-family property. As for obtaining a reference link for Arial Black, it is a system font that should be available by default on most devices and systems. It may not have a dedicated API link like some web fonts do.
