I don't see the option to unshare a folder, even though I'm the owner

Hannah, thanks for your help.  The ticket number is #24665307.  I have just been going around in circles for almost a month.  They keep asking me to resend the same information; they keep threatening to close the ticket unless I send them yet another screen recording of the same information that I already sent (I have already sent screen recordings three times, even though they entirely duplicate all the information that I had already sent in writing, and tech support is still demanding more), and they keep ignoring what I have written (e.g., most recently multiple times demanding that I send a screen recording showing what happens when I try to unshare the parent folder, when I have already explained at least half a dozen times that the parent folder is NOT shared).  I can't go on with a service like this that doesn't value my time (and doesn't fix issues). I cannot use a service that holds my service requests hostage by insisting that I spend endless time providing more and more information when I have already provided all the information needed.  Not valuing my time is a complete deal-breaker for me.  

This new policy of demanding screen recordings of everything is especially problematic--when did accepting any details in writing become obsolete? Screen recordings should only be requested by tech support when absolutely necessary, and only after Dropbox has actually looked into the issue as described. Sending screen recordings that provide identical information to carefully written details that have already been provided not only violates my privacy but wastes my time (not to mention introduces issues of accessibility for some users).  In addition, every time I give in and send a screen recording, tech support then inevitably tells me I need to send yet another screen recording (which duplicates what I have already sent) or they will close my case. 

I started using Dropbox when it first started almost two decades ago and had always been more or less happy with it (even if it sometimes lacked some features I was hoping for).  In addition to my Pro account, I recently purchased a Dropbox business account for my full team.  I now deeply regret this and am actively looking for alternatives for both me and my team.  Since then, the sheer volume of technical issues and built-in limitations to the programming (in both Dropbox Pro and Dropbox Business) for simple tasks (like the sharing issues here), and the subsequent mismanagement by tech support make Dropbox in its current form unusable by me and my team.  All I want is a system that will backup and sync my files reliably across devices, let me retrieve deleted or modified files for an extended period of time, and let me share and control permissions with others--in a way that is secure, reliable, and time efficient.  I'm not looking for other bells and whistles and I'm willing to pay for this service.  But Dropbox no longer seems to provide this...
