We are experiencing the same issues. Myself and my staff use Google Docs to communicate about sessions and for the past two weeks using an app (G-Whiz) or Safari forms have been saving as grammar/ word salad or not saving at all and there have been multiple error messages. We tried testing it on Safari again today and it worked for a test but not in applications this evening.
Any suggestions? There are no updates for our current OS or app for Google.
