iPhone hotspot - hidden network warning on MacBook

Hi, whenever I start hotspot from my phone to my MacBook, there's warning, that I am using a hidden network and I should change my router settings. But I did not change anything in my hotspot settings, in MacBook settings. I did update some time ago to iOS/macOS 26. I don't know if it is some bug? Or what. Please, do you know what to do? I've got iPhone 16 and MacBook Air m4. There is no warning on iPad or Apple TV.

Thank you
