Thanks, I finally figured out that's where people were seeing the issue. The expiration is for the security token issued by the application. Those have short lifespans and are refreshed when you go back into the application, so the expiration is normal and not reflective of an issue. But, people saw that a rumors spread like wildfire that our district let the "agreement" with Google expire without notifying stass.
After last night's maintenance event, I'm now able to connect to Google Drive from my account and one for a student that initially reported the problem. The last status update said: "Tonight's scheduled maintenance event is complete. Your users can now access and use the Google Apps LTI as normal."
