HI there @pukoboss - thanks for using Dropbox and welcome to the Community!
With the update you mentioned to the Dropbox Backup feature, it's true that you can't access your backed up files from the mobile app, but only though a web browser via the backups page.
If you'd like a folder or files to sync normally instead of being backed up, you can copy or move them into your Dropbox folder and have the desktop app sync your changes.
From there you'd also be able to get shared links for the files you like.
I hope this helps!
