Hello @DTS Engineer. Do you have any other suggestions? Or is it that persona profiles is such a terrible, backwards feature that even Apple engineers themselves flee from discussing them? Maybe that's why all the other posts I've come across seem to die on the vine, never seeming to come to a conclusion.. I guess it just magically works or it just doesn't f***ing work and no one comprehends why, including Apple.

Perhaps only direct responses to posts get noticed? This was not helpful (see below). Any other suggestions? Am I at least using the correct type of certificate / profile combination (which is "distribution" and "App Store", respectively)?
