I have the same problem when using Edge browser....... After switched to Chrome, the problem gone !
I'm not quite understand the apple certificate process, so every year when I renew my apple developer membership, I have to follow Erel's video again but this year I got some question :
In the past, I need two certificate and two mobileprovision files (ios_distribution.cer, Distribution.mobileprovision, ios_development.cer, Development.mobileprovision), but according to the updated video, seems now we only need ios_distribution.cer and provision.mobileprovision ?? Is that true or I missed something?
