I have 2 files, one is a copy of the other, FileDB1 and FileDB2. I accidentally opened FileDB2 when it should been FileDB1. I created a layout on FileDB2 and was well into the development before I caught my mistake. I attempted to create the same layout and theme in FileDB1, but found that the Theme and it's category were not available in FileDB1. I'm running FileMaker Pro 16 adv.
Category Theme Name
My question is where can I find the missing Themes?
