Why can’t I view my homework on connect, on my iPad Pro? How do I fix this?

That would be an issue to discuss with McGraw-Hill. I use SIMnet, another McGraw-Hill product, to teach computer classes at our community college, and the local school IT department does not provide support for those products, McGraw-Hill does. Depending on the content, I can display all of the content of my SIMnet work on my iPad. I know that it has been updated to no longer use Flash for SIMnet, however I'm not sure about Connect content. McGraw-Hill's support can answer your question. Use their help link and contact their support. You can either Chat or call them by phone, and they will work with you.

I understand you are trying to access your homework on an iPad Pro, and you are seeing instructions that a computer must be used?

Are you asking about the McGraw Hill Connect application for schools and universities? If so, you may need to check with your school's IT department about how to access the content. If this is not the application/service you are referring to, please reply to this thread with some additional information about your school and what you are trying to do with your iPad Pro, and we'll do our best to help.
Take care.
