Please see screen-grab below (BTW OK in Firefox on High Sierra)


Based on the old F7 logo, I think you have to clear the cache of your browser. I had the same experience but after clearing the cache the new F7 logo became visible witch one exception: the commercial (in your screendump “Topal”) remains invisible for me.

Yeah, just refresh/clear

Should have thought of that!! - Now its fixed and looking very good.
Just need to read carefully about changes to be made when upgrading from previous version (have new app release almost ready to go - so change now or later???)
thanks for the prompt response
