We use an app developed by UNIAPP. When authorizing the connection to Facebook and selecting a page, we cannot scroll to the bottom to select the page at the bottom. How can we solve this problem?

I need to long press and force slide to the bottom to see the page at the bottom, but because it is a long press, I can't select the page at the bottom at all. If I scroll down in the usual way, I can't even see the bottom page.
