I used my old phone when I travelled to share mobile internet with my laptop, just the normal usb a to usb-c cable that came with the phone. Now I used my pixel 7a and tried to use the same cable but it greyed out the usb tethering option, when I came back home it only worked with the usb-c to usb-c cable it came with. So I have to use a specific cable for the pixel 7a? Some people said on the internet it only works with usb-c to usb-c cause of regulations or sth that other companies don't care about, interestingly with the usb-a to usb-c cable fast charging works as well as with the usb-c to usb-c cable. Is there a cable that I could use to make usb-a to usb-c tethering work or I have to use the usb-c cable with this phone?
