I had the same experience while working on WP in 2012-13.

In early 2013, I reported a bug when some of the elements inside LongListSelector would disappear randomly on scrolling. LongListSelector is WP’s counterpart for iOS’s tableView.

So I started a discussion on Microsoft forums on this bug. Someone from Microsoft confirmed this bug.

I tracked this bug for 9 months. And guess what they never fixed it. They never fixed a critical bug in the most used UI component of mobile apps.
