A32NX EFB help required

Hi all, you’re so kind replying to my query. FBW dont support issues with custom or development they say. I can confirm I use the latest installer and yes I do have the FBW A320 showing in aircraft selection. I have over 250 hours A320 including some 35 with FBWA 320. I’m an old PPL using Microsoft since late 1982, love it. My last thought is an issue with simbrief not connecting but it does in the MCDU…which I always use. Using pilot number in EFB as shown in simbrief. I’ll keep digging, will advise if I crack this.
