I received a message from Instructure Support regarding the issues with outcomes / rubrics in Canvas. Please see the message below. It appears a fix is just around the corner:

Hello,

Your Canvas case 10662810 has been updated with a new message.

Hello, Our engineers have created a fix that has passed initial QA testing. The next step is for this fix to be deployed to our Beta environment, where it will be available for Teachers and other Administrators to test, and to ensure it is working properly before it will be added to our live Production environment. We will provide another update once the fix has been applied to the Beta environment, or if there are any other changes to its status. This ticket will remain in an "On-Hold" status at this time. We appreciate your patience throughout the process of testing and implementing a fix for this issue - if you have any questions about this message or the status of this fix, please feel free to contact Support. Keep Learning! Support Panda Notifier of Things

Thanks!
