Hey @nppvice Can you share a screenshot of your blocks please? Also, are you live testing or installing your app? Finally, are you using your own Cloudinary API key etc or are yo using Thunkable’s defaults? Thanks! ---

No blocks at all. Just a simple url pasted in file source of the pdf viewer. I am live testing. Cloudinary set up with my credentials. Webviewer works perfect if pdf converted to jpg or png. However, pdf is downloading unto my phone instead of displaying in webviewer. And the pdf viewer has error message. ---
