Turn OFF "Limit IP Address Tracking" for Wi-Fi and Cellular

This feature sometimes slows down DNS and link-speed on iOS 26.

Settings → Wi-Fi → (tap your network) → Limit IP Address Tracking → OFF

Then also turn off for mobile data:

Settings → Cellular → Cellular Data Options → Limit IP Address Tracking → OFF

Try a download again.
