We have experienced some issues with iPads and iPhones accessing resources such as textbook on ClassLink. We have had better success buy using the login URL here: https://launchpad.classlink.com/mypolk. When using this URL at school, students just enter their user name but not their full email. For example, John Doe would login with johnd43 (user name) without appending it with @mypolkschools.net. You may need the full email account name at home. After entering their passwords, students should click the “Sign In” button like the picture below and ignore the lower “school student sign-in.” For further information, please go the PCPS web page at https://polkschoolsfl.com/classlink/.
