Blocked Messages

[fagin84]

I updated a few apps which hadn't been updated in a while today or maybe I updated some software, I can't remember. Anyway, something changed and icons etc look updated. Since this update, one of my friend's messages keep going into the blocked messages folder, accessed via the dropdown menu in the message inbox. I remove them to the general inbox but 10 minutes later I see that they're back in the blocked folder again and this keeps happening. This contact isn't blocked in any way so I'm at a loss to explain this. Any help would be appreciated.
