All loaded emails show the same content

Steps to reproduce:

• Having configured an Email Folder, the user performs Check Email - Different emails are successfully loaded
• User checks first email - Content is shown
• The user goes back to Email Folder and checks a different email

Expected outcome:

• The correct email content is shown

Current outcome:

• Despite the correct email information (Sender, Subject, Send date, etc), the content is the same as the first one opened by the user.
• Browser console logs show the following error:

  Uncaught (in promise) DOMException: Failed to execute 'fetch' on 'Window': The user aborted a request.
