Acrobat times out when connecting to SharePoint server

Adobe Acrobat DC on Macbook issue.

I have two SharePoint sites which I had connected to Acrobat. But every few weeks the link seems to break and the software hangs at a blank screen. Only resolution is to hit ESC, then click the red X to close the blank pop up box, quit Acrobat, reboot the Macbook, make sure that OneDrive is logged in and synced, and then re-launch Acrobat and re-add both the SharePoint sites.

This is bloody ridiculous for expensive software and the insult is that there is no telephone or email support that I can find anywhere to get this fixed. I hope somebody on this forum knows what the problem seems to be as it does not replicate on the Windows version of DC.

Many thanks if anyone is able to assist 🙂
