This is just getting more and more frustrating...
Again, I've been super busy and have just gotten to retrying. As expected, it failed. Menu | Start Simulation Mode | Replay ADSB Recording does absolutely nothing. I don't even get an option to select a log.
So, go to send bug report but don't know which one to send, and the 2 reports mentioned below have both been overwritten.
I don't trust iFly to show traffic correctly on my tablet. If it misses this one, how many others is it missing? The offendign aircraft - 5199B - does show on my phone even connected to the same Stratux. So, it is definitely an issue with this particular tablet model. As you know, the previous one also had an issue displaying one particular aircraft, though a different one.
