Ask HN: Why is my iPhone connecting to TikTok, Amazon and Aliexpress?

[passwert]

After a HN post two days ago, I've installed NextDNS on my iPhone and started noticing random connection requests to *.aliexpress.com, live.musical.ly, amazon.sa and others.

What made me wonder is that a) I don't have "background app refresh" enabled, b) No app from TikTok, AliExpress or Amazon is installed and c) I had the phone locked ("standby") during the whole time.

Does anyone know what might be happening here?

It could be another app making these requests.

But with "background app refresh disabled", other apps (except maybe the ones from Apple) shouldn't be able to make any requests?
