The styling of Find hasn't been updated yet to support the new theme. It will be at some point
I asked Episerver Support, and they answered;
«There is an open task on this with our dev team.»
According to this blogpost, It shouldn't be that hard:
When episerver is updated (including CMS,Commerce,Find) to the latest version with all the dependencies , the backend theme has been changed.
The package EPiServer.CMS.UI is updated to 11.21.5v, but when find is opened in the backend it is redirected to the old UI theme.Please help me with this issue.
Thanks in Advance.
