I can't access my backup from other devices after a recent update

When I first started using Dropbox, I could see my Desktop, Documents and Downloads files in my Dropbox web and mobile application. In this way, I could add an attachment to an e-mail in my mobile applications or save the report in the finance application to my desktop.

You changed this process to Backup Solution.  I want to sync my Dektop, Documents, and Downloads folders as in the beginning. You are the one who transformed this into Backup and without any approval or information from me. This process should have been optional. Some users like me might want to continue as it is, have you ever thought about that?

Currently, I need to create my Desktop, Documents and Download folders in Dropbox, move all the contents to these folders and leave a file shortcut in their original place, but this is not a solution, I drag and drop each file I downloaded from the internet or saved from an e-mail attachment to the Desktop or Downloads folder at the original address. I need to remember the file and copy it into the shortcut so that it can be synced. I have to do this because when I say save a file to dropbox on my mobile phone, my desktop etc. folders used as backup are not included in the folder list that opens. (I used to see)

And I used to be able to share a folder on my desktop with other people. Now, due to the backup feature, I can no longer share these folders. I need to replace these too.

This situation is ridiculous. I want to use the Backup feature as before, but I don't want it. All I want is to be able to sync the folders I choose, such as Desktop, Documents and Downloads, in Dropbox without the need for any shortcuts.
