I still have the old DTTG icon on iOS in the Share sheet for some of my apps… one of the is Scanner Pro. I think there is a hidden icon somewhere in iCloud Drive that I cannot find. This is on iPhone and iPad, but I also found it in iCloud Storage/Manage on my Mac. Any ideas on how to change/update this?
 Upon further inspection, I just realized the Scanner Pro share menu is not the actual iOS share sheet, so for that app the developer may have hard coded the icon. I will ask them. But it still doesn’t explain the icon in iCloud Storage on the Mac.
