Google Classroom app - com.google.classroom.dataservice.client error -1

[hphan]

Hello,

Anyone receive this error com.google.classroom.dataservice.client error -1 with the latest Google Classroom app?

Students have been using the app without issue until we force the latest app update in preparation for iOS 12 upgrade. Many students have this issue with the latest version 2.2018.39208

Thank you!
