Adobe Signed Document cannot be viewed in Adobe Cloud

Hi everyone. I am running into some issues with views of my Adobe signed documents. I was hoping someone here might have already run into this issue and have resolved it. Did a search for the partial error that comes up, "not able to open this document" but nothing helpful came back.

When I use the Fill & Sign tool in Adobe Acrobat DC, I am able to sign and successfully upload it to Adobe Cloud. If I then share the signed encrypted PDF to someone who is not required to sign it but needs access to it via a shareable URL, that person can load the URL fine but accessing the signed PDF this way always produces the following error.

File Download
We're not able to open this document. It's either corrupted, or the file type isn't supported.

Downloading a copy of the file works fine and the recipient of the shared document can locally open the signed PDF file fine.

But what is the likely cause of the error above? I would be unable to send this document if any of my recipients do not have access to Adobe Acrobat Reader. This would happen in two scenarios.

Either (a) the company hasn't seen the need to install Adobe Acrobat Reader or (b) they are versions behind and the version they have cannot open the signed document without the most current version of Adobe Acrobat Reader? Yes, yes...I could try to persuade them to upgrade/install but that's outside my sphere of influence/control.

Anyone experienced this issue and how have you fixed it?
