If you are having trouble accessing apps such as Google Classroom, Google Docs, Nearpod, etc. on your DOE-issued iPad, then please visit the DOE's website. It provides alternate ways to access apps at the following link: https://www.schools.nyc.gov/learning/learn-at-home/technical-tools-and-support/getting-started-in-google-clasroom
Here is additional information about using the iPad to sign into apps:
Signing In to Apps
For all Microsoft apps, you should sign in with your DOE student account.
For all Google or G Suite apps, sign in with your DOE student account or the Google address your school may have given you already.
You cannot use your personal Apple ID. Your iPad is for educational--not personal--use only.
