Hi Glide Team, I have issue in Duplicating App. I chose Linked Table when I dupliceted it and I use native Glide Tables, hoping it will use just one for all app table, as seen in this screenshot: ![Screenshot 2025-04-28 at 17.04.07](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/8/a/8af490102b0d4cfa5c2141ba6d1a37b98c13c62e.jpeg) But, when I updated by adding a column in the duplicated App, the original App is not adding the new column (that I already refresh it many times). ![Screenshot 2025-04-28 at 17.07.36](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/0/9/097980332d68eceb2864a4e55c8df5c0ff7ddc59.jpeg) Not showing the column ‘TestDuplicate’ in the original App’s table. ![Screenshot 2025-04-28 at 17.07.23](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/2/5/257b49e851f61a014b2fbc71e4ccf50d9972fa60.jpeg) I really hope it will be easier to sync data with Glide’s native table instead of using Google Sheets, as I’ve done in my previous projects. Somebody help? ---

The column you added is a computed column. Computed columns do not sync between linked tables. Only non-computed columns will be kept in sync. To understand more, have a read of the below. It’s quite old, and some of the terminology has changed, but the information is still accurate. > [@Relationship and References Created in Glideapp Table](https://community.glideapps.com/t/relationship-and-references-created-in-glideapp-table/49119/5): > > The way your question is posed is a little confusing, so I won’t try and answer it directly. Instead I’ll explain how it works, and maybe that will help. First thing is that it’s important to understand the difference between Basic and Computed columns. Maybe you already do, but it’s vital in this context so I’ll explain it anyway. Basic Columns are those columns that contain actual data, as opposed to data that’s calculated from other columns. Text, Email, Image, Date/time are all examples o… ---

So I have to ensure that I will do the computed columns _again_ in the other App if I needed it. Got It! Thanks and appreciate, Darren! ---
