The mobile provision you are using does not match the id of the app you are building.
Not entirely sure about this one , but it is problably related to the first error. Whenyou built the mobileprovision did you use the signing certificate that you have included in the app?
I'm trying now on a new phone.
Iphone 12 Pro.
I registered the phone on developer.apple.
I created a new certificate, identifier and provision.
But I Cannot Install the B4I, I received the following error "Unable to Install "B4i-Bridge". Please try again later."
I'm sure that I registered the right udid.
I have done this procession twice the last hour.
Furthermore, as I read in the forum, I think that first I have to install the B4I-Bridge with the default provision (as Erel's example), and then I have to try to run my app (notification app).
Any suggestions?
