can someone tell me what the red triangle that is displayed for some of my projects in desktop mean ?
Hello! It should show a tool tip message if you hover over the red triangle (at least, mine did), but it usually means that it can't find that database any more and that it has somehow been removed.
There's a fix to remove it in your list by open the app folder on your system and removing the database from the persist databases.json file. Steps are in this message: Remove DBMS that now longer exists on FS - #6 by nglgzz
Let me know if you need anything else!
