I don’t know if this really needs to be fixed, but I’m seeing this warning in the console:
[Warning] [THEME 203 'Sticky New Topic Banner'] (chunk.c299dadf3652266cf24c.d41d8cd9.br.js, line 47)
"Deprecation notice: controller:discovery/topics no longer exists, and this shim will eventually be removed. To fetch information about the current discovery route, use the discovery service instead. [deprecation id: discourse.discovery-topics-controller]"
