Gray vs Blue Database Icon Color
What's the difference between databases with gray vs blue icon colors? I have several databases, all cloud based. Some display as gray, others blue. My understanding is the color difference has to do with "device ownership". I have tried to "Reorganize" gray databases to set ownership to my Macbook Pro. Ninox will briefly change the color to blue and then it goes right back to gray. I don't see any difference in ability to edit the structure of the database (in fact all the databases have been created and managed on the Mac), so what's the difference and why won't the gray databases "Reorganize"?
I'm using Ninox on MacOS, iPad and iPhone. All databases are cloud type through iCloud.
