Hello, I have noticed despite on my Mac connected to the same WiFi network would connect to the fastest routing via TPE server. On multiple iOS devices I tested NextDNS using either app or profile would always defaults to Hong Kong server despite significantly higher latency. Here is the https://ping.nextdns.io results.

  estnoc-tpe       18 ms

  navico-han       28 ms

  anexia-hkg       35 ms

  vultr-tyo        57 ms

  zepto-tyo        57 ms

  premiumrdp-sel   84 ms

■ zepto-hkg        90 ms  (primary)

  serverwala-kul  103 ms

  premiumrdp-kul  125 ms

■ vultr-sin       133 ms  (secondary)

  zepto-sel       368 ms

Even when connect to cellular that has IPv6 enabled TYO server would still be a much better choice than Hong Kong with averaging more than 30% faster response time. In the past few months TYO server is how my iPhone would route; however, this has also change to (always?) use slower Hong Kong server instead recently.

Since I’m on mobile device I can’t produce log file as the troubleshooting post has suggested. I hope this issue get resolve soon.
