Outlook Customer Manager - Companies do not display in the list

Unfortunately I have wasted alot of time trying to make what looked like a simple but effective solution work for my team but ran in to issue after issue - it seems this tool is not stable enough to use. 

This is just one issue. The same issue occurs with Deals. Also, when I imported the contacts, the company names assigned have an exclamation next to them saying they have been deleted or not shared with me. I edited the company name and made sure it was added and shared and did this for all contacts and their companies. When I rebooted , they were all flagged again with the same issue.

I cleared the internet cache several times . I tried loading manually but still have the issues.

My teammates do not see all the contacts I added even though they are all shared.

No response from forums on these issues and I see many others have the same issues and more . I submitted feedback through the app with no response.

And the roadmap does not mention OCM at all .

I have given up on OCM and am evaluating  other tools now which is frustrating since we have paid for OCM with the O365 business premium subscription.
