Hello Shanhua
I looked at your site, it appears you have not figured this out… I’ve been having the same issue and found out how to fix it…
In the App, go to GENERAL SETTINGS
Scroll down to the 3rd section, LIST SETTINGS
The 2nd setting, SHOW VIEW (Render the view entry icon) needs to have a checkmark.
Click APPLY and test.
This fixed the issue for me.
