Hello, fellow Glide users! I am facing this issue where sometimes the Unique Values function returns a LONG number and other times a uuid unique key. For example, uuid - 087f8d5d-890e-43ab-98f0-5924fe16e281 Long number - 2,021,572,464,689,270,000,000,000 Am I making a mistake or is this a bug? Can someone please help. ---

Check your column types. If you write a Unique Identifier to a number column, you will get a number. ---
