@FikriMilano any updates on it? thanks!

[FikriMilano]

@santosh-pingle not much update, I was logging the logic and doesn't found anything wrong.

Still investigating, but I have a conjecture that it's related to the recycling of recycler view

[santosh-pingle]

@FikriMilano similar issue was found in #1818, may be you need to clear the old state before binding the data to the item.

[FikriMilano]

@santosh-pingle I have created PR #1828 to close this ticket.

Yeah, it turns out we need to clear the preview if there is no answer. And it has to be declared when binding the view holder.

[FikriMilano]

The reason why the other widget is also seems to be uploaded is because it recycles from the top widget, which already been uploaded. But if we click Delete at the other widget, it crashes because the answer is null. So it only recycles the view but not the answer.

[FikriMilano]

So, yeah, by clearing the preview if there is no answer will fix the bug
