Sorry I gave you bad info again. I forgot that S0 only devices just go secure without asking. Not very often I include a S0 device. Sorry again! I am used to seeing that prompt on every pairing.
The most common issue people have with pairing locks is from selecting no security, that's why I kept mentioning it!
I fixed my posts above in case someone else finds this so they don't get confused.
I was really quite terrible at helping this time around
