So I often work with people in different countries and we often have different unit preferences. I work in mm but when I open files from fellow creatives in America for example, they are often using inches.

Now I thought that my preferences being set to mm would mean it would show the files in mm, but apparently this only applies to new documents you create, not to existing files. This seems so crazy to me given the digital, remote working, globally collaborative world we live in today.

Please could this be a thing because going into the settings every 5 minutes to switch to mm over and over again is driving me crazy. I can't possibly be the only person having this problem??
