I've tried everything mentioned above and it still doesn't work. I would appreciate if someone from either Apple or Google came up with an answer that really functions.
No one from Apple or Google is going to answer you here. This is a user-to-user technical support forum. Also, it's likely that no everyone in this thread is having the same problem. So, there is no "one" solution. If you want support from Apple, either make an appointment at the Genius Bar at your local Apple Store or click on the "Contact Support" button in the upper right of this page. For help from Google, start here:

When I try the calDav solution, I get a validation error. There's a fix proposed by Google that involves using Exchange rather than Google as the account type, but that doesn't work either. I've tried it on WiFi, I've tried it on 4G. No difference, same results.
CalDAV hasn't been required for Google accounts in years. You can only use Exchange if you have a paid Google account. If you have a free Google account, it's simply not an option.
Do you have two-step verification enabled on your Google account? It complicates adding the accounts to an iOS device. I've rather forgotten the process but, I followed the instructions above.
Best of luck.
