@JasonFisher The ‘one way sync’ part is just for those certain sheet as indicated in the original post. Automatically generated sheets, such as ‘App: Logins’, ‘App: Comments’, and ‘App: Sales’, are created by glide and added to a google sheet a sort of log only for your use. They serve no function to be used in a glide app. You can duplicate those sheets if you happen to have a need for them to show up in your glide data, but for the most part they are just data logs, or transaction logs and thus only sync from glide to google. This is not the case for other sheets of data as they are synced both ways.
Now if you created your data in a Glide Table, then to data is stored only in glide and eliminates the need to have the data in a google sheet. If you would prefer to have your data in a google sheet, then you will need to Export the data as indicated in a post above, add that data to your existing app google sheet, then rebuild the logic to point to that new data tab. There is no easy way to “convert” data to be Glide Table to Google Sheet based and vice versa. It will take some reworking of existing glide computed columns, tabs, and any other layouts that were based on that existing glide table.
