Dave, I don't think it's anything to do with the beta version and I'm still convinced you didn't actually do things correctly. There may well still be a problem but it's not as you describe when looking at the log.
I've shown the relevant points from the log below... all of these took place within 2 minutes after reaching WP 13 (5420N), where you gave your position report, and at 160+ miles from WP 14 (DOGAL) where you would cross from Shannon Oceanic into Shannon Control airspace.
Your position report at 54N 20W WP13

These show the distance to DOGAL and the COM radio frequency
13/09/2023 18:16:17: 340 - Current Waypoint No: 14 Dest: 32 iLanding: 0 iClimb=2 Dist to next WP: 165.0219
13/09/2023 18:16:17: 340 - Ground Altitude=0 ClrdAlt=37000 Terrain=0 COM=123.95 Trans:2000
Then you changed the COM frequency to 127.5
13/09/2023 18:16:19: 380 - COM Changes at #1

13/09/2023 18:16:20: 390 - Ground Altitude=0 ClrdAlt=37000 Terrain=0 COM=127.5 Trans:2000
Then you hit Hotkey #0

They INCORRECTLY Answered... although I'm not sure what distance you could actually reach them

The you were told to re-contact Shannon Oceanic, but on the wrong frequency

So yes, there were a couple of issues here but it was, I believe, because you didn't follow instructions correctly. I'd like to see how PF3 performs when you do so and then I'll see if I can handle a case like this when there's pilot error.
