I have been testing SharePoint 2019 and I have a question related to Modern User Interface PDF Viewer Configurations.
On my SharePoint 2019 On-Premise environment, I have Office Web Apps Configured but we don’t want to Open PDF in the Office Web-App, we want to open it in the Client Application.
In the previous SharePoint versions, I used the commands below:
• Get-SPWOPIBinding –Application "WordPDF" | Remove-SPWOPIBinding -Confirm:$false
• Did an IIS reset.
• Cleared browser Cache.
