No, but because it's all made so difficult.
Lack of documentation and consistency.
I spent ages in the aircraft, with the engine running, looking for the "Tracks" icon, finding no documentation as to where it was or how to find it.
Having to ask ChatGPT, getting home to find nothing useful on the website, trying to log on to the website to be told that I couldn't have a login in unless I agreed to accepting marketing emails, and not being able to uncheck that once I am logged and, having been through all that, there still being no way I could find to download the log files, so, presumably, the only thing I have achieved in an hour of faffing around is more spam.
Very little to do with absence of callsigns, but I am very aware that SE2 and SafeSky, my previous solution, "just works".
Since you ask...

Oh, and yes, Garmin TAS shows callsigns, since you asked what you thought was a loaded question!
