Search opens but results are unexpected
Arden submits to Blogger’s normal site search. Check the query on the resulting Blogger search page and make sure your posts contain the terms readers are likely to search for.
A dark color seems unchanged
Switch the preview to dark appearance before editing the dark palette. Light and dark colors are separate.
A Theme Designer width seems unchanged
Use a wide preview. Available browser space limits site, reading and sidebar widths.
Custom CSS seems to override a control
Check any code you added in Blogger’s CSS editor. Custom CSS can override Arden’s normal Theme Designer values.
The appearance choice does not seem to persist
Try changing the mode with Arden’s header toggle and navigating to another page. If the browser blocks storage, Arden may fall back to the device preference instead.
