Unable To SAVE stories since update

Your recent update has broken the option for me to update/save my stories.

Deleting a slide and adding a new one to a published story and then hitting the update button has it spinning without end, rendering it impossible to do work.
No matter which story, the issue persists.

Need help asap as we were hoping the new update would have fixed previous problems and not made it worse.

Thanks.
