Tag information get lost after saving as ppt


while saving a presentation as ppt all tag information get lost.
But in previous versions it works. We use version Aspose.Slides

Here the code to reproduce it:

Presentation p = new Presentation();
p.Tags.Add(“test”, “test”);
p.Save(“error.ppt”, Aspose.Slides.Export.SaveFormat.Ppt);
Presentation p2 = new Presentation(“error.ppt”);

The message is empty.

Kind regards,

We are sorry for your inconvenience,


any estimation when it get fixed ?
We have a lot of customers who cannot work with ppt anymore.
For us, it is a hard regression because it works with previous versions.

Kind regards,
