When I'm editing my files from one computer that in a folder on my desktop or anywhere on the computer I can save them but when I swap to my other computer (Both computers are the same login and credentials, all under the same Adobe account as well.) I get a error code the file may be read me only or save with a different name or in a different folder. If I place the document on my desktop and edit the file I can freely work from one computer to the other. Why is it like this? Can anyone answer this question.
Sorry for the delayed response.
Try disabling the preview pane as the following link suggests and check if that resolves the issue:
Also, let us know the dot version of Acrobat and the operating system installed on the machine? You may refer to the steps given in this link on how to check the version in Acrobat: Identify the product and its version for Acrobat and Reader DC
