I can't disable "Wi-Fi Assist" on my iPhone 7 (and "Use Parental Controls" doesn't work)
My Wi-Fi Assist is stuck in the "on" position and I want to turn it off.
I followed the instructions on this link...
https://support.apple.com/en-ca/HT201304#allow-changes
to the letter, and the "Wi-Fi Assist" sliding button is still grayed (greened) out.
Oh, help!
