Hi Aspose. I’m facing an issue trying to get a slide’s thumbnail. It hangs for a really long time with no result. There were no such problems with version 20.3 Here you can find a source project.
I have been able to reproduce the issue on my end and a ticket with ID SLIDESNET-42164 has been created to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.
