It's going to be allowed in NA and UK for sure. Apple will likely charge a fee to "verify" a third-party .IPA, but it won't be mandatory, and it doesn't go against the regulation. It will require you to enable developer mode which is already in the settings. I was talking to my team about this yesterday, we work for a large app development company and this is what they are expecting.Can't wait for 17.4 so all of these side loading questions can be answered... Will it be limited to EU? Are the reports true that Apple will still review each app and charge for it? <----- Doesn't that defeat the whole purpose of this regulation? How will this be implemented......... A .4 release is usually pretty boring but this time around its exciting. Cant wait!
