Instance limitations on published applications with HTML5 browser

[Jens Strohschnitter1709152492]

Opening several published applications with HTML5 client, only one instance/tab is opened.

So any new application launched from workspace closes the first pulished app.

 

For example, I open MS Access which launches in a new browser tab. Open MS Excel, the MS Access tab is closed/overwritten by MS Excel.

 

I've found this very old article:
https://support.citrix.com/article/CTX223569

This explains my issue. But checked out MS Edge / Chrome / Firefox. All of them have the same issue.

 

Is this an missconfiguration in the HTML5 configs on the SF server ?
