Summary: since the B4I-Bridge app suddenly opened and closed immediately without any error message (sich), therefore unusable, as I posted the first time, I uninstalled it and tried to reinstall it, I followed the instructions in the Erel link, or rather I think I followed them, I attach an image, but I was unable to install the app with either of the two mobileprovision files, in the previous post I reported the messages I had. It seems that some settings are missing but I can't figure out how to do i. I hope I have been exhaustive
