We recently switched from a file server environment into SharePoint. A problem our team members have is that they are unable to share a link to a PDF, and have that PDF open directly into Adobe Acrobat. We have the browser extension, and can open directly to Adobe Acrobat if they select "Open -Open with App" but that only works they open the file directly from SharePoint. In our case, they are using shared links. Having the option to open those files directly into full Adobe Acrobat would save our teams a lot of time.
