We are using an app on Azur to create and send emails.
The app receives data from the client, creates a PDF, download it back to the client, and sends it by email to the customer.
The app was created and installed few years ago, and it worked up till few months ago.
The app does generates the PDF and download it to the client, but doesn't sends the emails.
I want to debug (see in logs) why it doesn't send it.
How do I do it?
Please note that I am not familiar with Azur, so I need a specific guidance how to enable the logs and how to view them.
