What Grafana version and what operating system are you using? - CentOS & 8.4.4
What are you trying to achieve? - Upgrade to 8.4.5+
How are you trying to achieve it? - Normal Upgrade
What happened? - When we upgrade to anything above 8.4.4 the dashboards all lose their values and the tiles all become Grey. I can go into a tile edit, and can see the value, save and refresh the page and its gone again.
What did you expect to happen? - normal tile behaviour
