I am experiencing the same issue, no advice from this from Apple Enterprise support.
I have tried a mix of DEP profiles with some limited "skip" functions enabled and also a blank profile to no avail.
In the first, the setup of the iPhone is very quick and there is no data transfer
In the second, the setup gets stuck at "Setting up your Apple ID" and stays like that for hours!
This is really disappointing
Anyone found anything about regarding this? I'm not a dev, but I've got 60 phones to replace with users who don't have icloud storage and found out this isn't an option anymore.
