Recently (I don’t know when it exactly started, but probably around the introduction of iOS 13) I’m unable to use a Personal Hotspot on my MacBook Pro, from either my iPhone or my iPad (with cellular capabilities). This worked fine in the past, but while the MacBook still connects to an iOS device, it will now not have any internet connection. I also tried using the hotspot from my iPhone on my iPad and vice versa, with exactly the same behaviour: connection, but no internet.
I have already emailed my provider whether they changed anything in my mobile subscription recently, but it usually takes them up to a week to respond.
Anything else I can try in the mean time?
