Same. It started happening yesterday afternoon for me. First I randomly got a message saying “iTunes is running in safe mode. Visual and device plug-ins you have installed have been temporarily disabled.” All I had done was connect my phone to my laptop to charge, which I’ve done several times in the past and haven’t had this issue.
Reached out to support, and they recommended I try logging out and back in, and that’s when I started getting this issue. No matter what I do, I keep getting the “Genius results can’t be updated right now. The network connection was lost.”
I talked to multiple people in support today, one of which had me reinstall MacOS, which took an hour. He said he was sure it would work. Surprise surprise, it didn’t. He said that if it didn’t work to call back and ask for tech support. I did, however the woman I was put on with refused to transfer me to them, insisting that she was going to do everything she could to try and work on it with me herself. The “everything she could do” was basically a bunch of stuff that other people had already had me try. She then told me she was going to do some research and she’s have to call me back.
I’m relieved to know that I’m not the only person having this problem. Hopefully the more people that report this problem, the better our chances are of the Apple support team seeing it and hopefully fixing this. It’s very inconvenient, and the amount of time I’ve spent having people tell me the same stuff has been frustrating to say the least.
