I have 5 dashboards where over 30 reports are pinned. I have this setup repeated over 6 workspaces for different customers. I was about 1/2 way through pinning the 30 some reports and ran into this on 6 reports. Only 6. All 30+ have the same custom Advance Card yet only 6 are not pinning. This is as of 2:00 ET 1/26/21.
