I am using EMBEDPDF plugin (google viewer) on my joomla (3.9) site. I use it to show about 2000 pdfs. Each pdf is shown in an article so I have about 2000 articles.
When I open an article the plugin sometimes doesn't load the pdf correctly and what I get is a blank page. So I need to reload the page two or three times to see the pdf correctly.
I noticed that if I delete the joomla cache the plugin works better but only for a short time.
How can I improve the performance of the plugin?
Thank you for your help
