Uninstall this App using PowerShell will not work!

Hello,

I have try to uninstall a SharePoint 2013 App. with this PowerShell Command:

• Get Instance of Not-properly installed App’ Instance as following :
• $instance = Get-SPAppInstance -Web http://mysharepointSite/ -AppInstanceId‘f14876c4-26bd-41ea-8480-7a529882dd60′
• Uninstall-SPAppInstance – Identity $instance

It did work perfectly for SharePoint hosted apps.

For auto-hosted Apps it didn’t work as it is waiting on some Job to be finished before It can uninstall this App. “Another job exists on this instance. Please retry after that job is done.” this error message appears as below:

How can I remove the App in a On-Prem Installation?

Best Regards, Ralf
