We haven't updated our theme settings in hub, but want to change our logo & theme color and it is not letting us.
Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.
If you want to change the theme or logo you need to update first.
