Current implementation (v4.13.0) does not allow to do partial updates on a RecyclerView item, because the MoPubRecyclerAdapter never notifies the respective methods – See
https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter.html#onBindViewHolder(VH, int, java.util.List<java.lang.Object>)
I have created a PR to fix that – https://github.com/mopub/mopub-android-sdk/pull/237. I have tested on the sample app and it works
Can you guys have a look at that please?
