HELLO!
Sorry I forgot to check the forum for a while. Did you already figure this out? If not, go to your privacy settings and change “Allow apps downloaded from:” to “Anywhere”

This should solve your problem, but if it doesn’t then I am so sorry you have to perform a ritual where you smash your computer with a specific kind of crystal and then use either your own semen or the semen of another human male to glue it all back together. It’s just a minor design flaw but the spirits in the computer code seem to require the sexual energy of a human male to work properly sometimes.
