Safari Experimental Webkit issue on second hand iPhone
I bought a second hand iphone and see this experimental webkit so I reset to default at bottom of page, but don’t want to transfer to new iPhone if its linked to old man Joe’s MAC somewhere? I don’t think phone was reset to factory defaults because what do I know about iPhones years ago? Very few answers from Apple Support or TIPS.. so does anyone in the Community know? Shared Workers? API casting? Help? Safari?
