Solution 40355:TI-Nspire CX II Connect To Google Drive Option Does Not Auto-Check Access Checkbox and Displays Error 400.
Why does the TI-Nspire CX II Connect Save To Google Drive feature not working as expected?
TI-Nspire CX II Connect when clicking [Sign in with Google] or [To Google Drive] will request you to check a checkbox to allow the website to access your files:
The checkbox “See, edit, create, and delete only the specific Google Drive files you use with this app.” is not checked by default and must be manually checked.
If this checkbox is not checked and you click [To Google Drive] you will be asked to sign in repeatedly until an error 400 is displayed.
To fix this issue follow the steps below:
1) Click [Sign in with Google] icon and choose the option to [Sign Out]
2) Click the same icon to sign in again and enter credentials.
3) The permissions dialog will appear click it then select [Continue] after this is done the feature will work as expected.
