This issue is still there, and the support response is as generic as it could be.
I have a similar issue to what was described, but more for the top of the app (and the notification bar). I created the following post in the forum (Default color of the notification bar does not match) and have also opened a support ticket. They stated they will be looking into it.
I was hoping some of these issues won’t be there in the new “responsive” mode. I was ready to rework the whole app in the responsive mode, if that resolved the issue. But it seems that is not the case. Really sad to see that this has not been resolved for so long by Adalo.
