Update: We have released a temporary workaround for the Microsoft deployment issue affecting the Workpapers add-in.
Microsoft has expedited a replacement version of the Workpapers add-in that installs as a new Excel add-in, bypassing the caching and update issues impacting the current version. Internal testing and customer validation have confirmed that it provides the same functionality as the existing add-in.
Customers can deploy the replacement add-in through the Microsoft 365 Admin Centre using the same deployment process as the current add-in. Deployment instructions are available in the knowledge base article below.

We continue to work with Microsoft while their engineering team investigates and resolves the underlying issue with the original add-in.
