Hey there!

If you are getting this message while viewing a pdf in a browser, you are most likely trying to open a Dynamic XFA (XML Form Architecture) PDF. To view such pdf documents, we recommend you to download the file locally and open it either in Adobe Reader or Adobe Acrobat.

Here is a complete article on this: https://community.adobe.com/t5/acrobat-reader/pdf-won-t-display-please-wait/td-p/4788543 

Thanks,
