I’m in the same boat, Rodney. I cannot release some core updates due to this and since I am very sure it is on their backend, can do nothing about it. I don’t develop on a Mac so there is no way for me to build the iOS update.
I have had a ticket in with the Ionic Support Team for 4 days and have heard nothing back on this issue. This is very frustrating. Nor have I heard back from them (even to indicate they are working on it) besides the initial response that the ENOSPC error should be fixed.
