my platform. SharePoint 2013 with CU July 2019 + Office Online Server. All apps work fine and add-ins load. The problem comes when updating the SP CU and it has stopped working, giving the error: Please add or enable add-in catalogs from Trust Center

Only the CU has been installed, nothing else has changed from the platform. Any ideas?

    Hi @Thor El Poderoso ,

    Please try to check the settings under File>Options>Trust Center>Trust Center Settings>Trusted Add-in Catalogs for this specific user. And make sure that "Don't allow apps from the Office Store to start" is unticked.

    Hi

    That's what's weird. that there are no error messages in the ULS log. Everything is OK.
    The CU was updated a few days ago, from KB4475561 to KB5002202 and kb5002189, to leave the SP updated
