Question missed:
Attachments not enabled on your forum. May I ask why not? It is just one more step, in my opinion and makes the board less useful.
Next point:
The graphic below was observed after these steps:
1. Waiting for Motion Events list to populate (takes a long time with my setup).
2. iPhone went to sleep.
3. Unlocked iPhone, this is what appeared.
Note: I do observe a screen similar to this when system notifications appear when I am in the Motion Events screen in the past, but not in this specific case that I have documented here for you.
