In-house Distribution (Urgent Help!)

Hello Everyone,

Even though our enterprise account expired, our app associated with this membership said to run for the next 44 days. However, today all of a sudden, our clients are not able to open the app, it says 'This app cannot be installed because its integrity could not be verified'. Note: we did not build and deploy any app ever since the membership expired. Our clients were able to download and install the app until today. Any help will be highly appreciated.

Thank you!
