@Paradoxxx

I had same problem, my PA2 stops after startboost and i find what's wrong but don't remember exactly what was that..
After reset all config in AQ5 and PA2 i do what i told you all works fine so i don't have any better idea to help you, sorry.

If I find something I will know for sure.

If u want I will make photos of configuration on my AE5..
