I spent the majority of my day on the phone yesterday with AppleCare support, and I have come to the conclusion that Apple doesn't care. They were so adamant that there wasn't a problem, and were so adamant on passing the buck to the carrier, the ftp software, anything but admitting that there is an issue. To recap, I have 2 Apple laptops running 2 separate OS systems. Before I upgraded to iOS 17 everything was flawless. After changing to iOS 17, everything went to crap. My computers would connect hardline, or with any wifi, even the free ones at McDonalds without an issue to any ftp site. But the second I try to use my phone's hotspot, it won't connect. Another photographer friend of mine has the exact same issue after updating his phone, so we troubleshooted. I'm on AT&T, he's on Verizon. I use Panic Software's Transmit, he uses FileZilla. He logged into my phone, no connection. I logged into his phone, no connection. Apple Support said to contact the carrier, it must be an issue with them. I did, no problem at all and actually, using my phone and his, I could get on the internet and access email. I just couldn't connect to ANY server. So I called Apple back, told them I spoke with AT&T and there was no issue and gave them the tech support case number from AT&T. So then It magically became an issue with the ftp client. But it is happening on 2 different clients, on 2 different Mac OS's on 2 different carriers. The only common denominator is iOS 17. I truly believe that Apple has a bug in the system, and are doing their best to pass the buck because they don't release faulty operating systems. Well, there are way too many of us having the exact same issue for them to be ignoring it or passing the buck. Come on Apple, there are people that their jobs rely on using their phones as a hotspot to transfer data, and you are letting a lot of people down.
