I was setting up my wife’s new iphone yesterday and afterwards I noticed that on Software Update she has the 2 options available - Customer and Developer beta. She has never had a beta or a configuration profile on her devices nor associated with her Apple ID. After seeing this I went to her iPad Pro and saw the same on it. Both are now on 16.4.1. Those options are on my devices but I received an invitation to the AppleSeed beta program ages ago and have used the configuration profiles until 16.4/.1. I was assuming that only those who had done so or used the public betas would have these options on their devices. Apparently I was mistaken. Do all devices on 16.4.1 or later now have beta options under Software Update?
