Any sheets that I have created in the same app, they disappeared after I load some new data, the only sheet remains are the latest one I created.
Have I done something wrong? or the script is not correct? I am using Personal Edition.
That's not normal behaviour, but its hard to diagnose why without more information. Can you upload the qvw file? Perhaps before and after loading.
It looks like it's a connection issue, I was working from home when I got the issue. Everything was fine when I am back in the office. Very strange.
