Yes, but it still deserves the question to be asked explicitly. I don't think most iPhone users looking for a music reccomendation app would assume they'd need to selfhost in order to use an app.
And again, if as the dev he's not prepared to set up his own server for use to pass basic testing, it begs the question of what exactly he's expecting out of his end users and if it's truly a reasonable ask even if they're prepared to self host
If by countless you mean 8 valid ids of this same singular issue in 100 runs, with an almost 30% false positive rate, then sure.
I'm far more worried about the false positive rate drowning out things.
