Hope everything is going well.
I am writing to kindly inform you of the current case status.
Based on the research we have done, we have found that part of your question has to do with Adobe. In order to proceed further, we must engage the Adobe community, as there is a lack of expertise and information about Adobe in our forums.
During our search, we found certain official documentation related to integrating Adobe and file saving in SharePoint Online. Please check if these are helpful for you:
Access SharePoint files in Acrobat, Acrobat Reader
Install Acrobat for SharePoint and OneDrive
