If you are using Infinite Campus Instruction and are also using the Grammarly App, you may run into the following error message:
Support has assigned it as bug SIS-126349.
To fix this, you can remove the Grammarly extension or set it to run 'When you click the extension' only.
Another alternative that we found is uninstalling Chrome (version 74) to an older version. (you can enter a work order for this to be done.)
