I set up my business on Google many months ago and it still says pending review. I also cannot see any reviews from clients on the dashboard, but they are visible on Google search.
Some Google Business Profile approvals require manual review - this is entirely normal.
At the present time it may take longer than usual, so other than having patience, all that I can advise is to make sure that your business is eligible for a Google Business Profile, and that you are following all of the GBP guidelines: https://support.google.com/business/answer/3038177.
