Some migrated-from-Confluence-Server CODE BLOCK macros display intermittently as empty boxes.
Some pages containing Code Block macros intermittently display these macros as empty boxes after migration from Confluence Server to Confluence Cloud. Usually this corrects if I click my browser's REFRESH button (I'm using Edge browser but have also seen the problem in Chrome). Correction is not permanent: If I skip among several pages showing the problem, the empty boxes are likely to return on pages previously fixed by clicking REFRESH.
