I don’t think we have the ability to remove a Google Sheet as a data source, as of now.
If you have not permanently deleted it, maybe you can go to your “Trash” folder in your Drive and restore the file?

Hi @Dieselone_Group, I notice that your home screen is a details layout and you have x3 inline lists there. If you have many records in each of these inline lists, it could explain your app being a little slow. I would not expect it to be _very_ slow though.
As an example, recently I built a screen with about 15 inline lists and a total of about 100 records on the screen. The scrolling behavior was not smooth. The performance improved when I replaced the 15 inline lists by one single list where I used grouping instead. I understand you cannot always find such an easy solution, this is simply an example.
