🤔 Problem
If I switch my Jira dashboard containing a Bar Charts gadget to wallboard view, the gadget doesn't show at all.
🌱 Details
Currently, there is no solution for this available since Atlassian does not offer wallboard rendering for Forge apps.
You can still have a look at Atlassian's open ticket about the subject and vote for adding this feature or inform them about your use cases for the latter.
