If I switch too fast in 5 seconds on mobile chrome, useEffect will not fetch data from openWeatherAPI.
But wait it for 5 second and reswitch page, it is ok to fetch and display.

My weather app by Next.js app route deploy on vercel has two pages “/”, “/week”.
I use getPosition() get lat and lon, fetchApi() get weather data, and <Link> to switch pages.

homePage(“/”)

"use client";

import { fetchApi } from "@/api/fetchApi";
import InfoBox from "@/components/InfoBox";
import RainChart from "@/components/RainChart";
import TempChart from "@/components/TempChart";
import { getPosition } from "@/utils/getPosition";
import { unixToDate } from "@/utils/unixToDate";
import { unixToTime } from "@/utils/unixToTime";
import { useEffect, useState } from "react";

export default function Home() {
  const [date, setDate] = useState<string>("");
  const [time, setTime] = useState<string>("");
  const [desc, setDesc] = useState<string>("");
  const [feel, setFeel] = useState<number>(0);
  const [hourFeel, setHourFeel] = useState<number[]>([]);
  const [hourRain, setHourRain] = useState<number[]>([]);

  useEffect(() => {
    getPosition()
      .then((position) => {
        fetchApi(position.coords.latitude, position.coords.longitude, "metric")
          .then((data: any) => {
            setTime(unixToTime(data.current.dt));
            setDate(unixToDate(data.current.dt));
            setDesc(data.current.weather[0].description);
            setFeel(Math.round(data.current.feels_like));

            const hourFeelData: number[] = [];
            const hourRainData: number[] = [];

            for (let i = 0; i < 24; i++) {
              hourFeelData.push(Math.round(data.hourly[i].feels_like));
              setHourFeel(hourFeelData);

              hourRainData.push(Math.round(data.hourly[i].pop * 100));
              setHourRain(hourRainData);
            }
          })
          .catch((err) => {
            console.error(err);
          });
      })
      .catch((err) => {
        console.log(err);
      });
  }, []);

  return (
    <main>
      <div className="mt-5 flex justify-evenly">
        <InfoBox date={date} time={time} content={desc} />
        <InfoBox label="現在體感" content={`${feel}℃`} />
      </div>
      <TempChart data={hourFeel} />
      <RainChart data={hourRain} />
    </main>
  );
}

import { fetchApi } from "@/api/fetchApi";

const WeekPage = () => {
  const loop = [];

    loop.push(i);

  const [date, setDate] = useState<string[]>(["", "", "", "", "", "", "", ""]);

            for (let i = 0; i < 8; i++) {
              dateData.push(unixToDate(data.daily[i].dt));
              setDate(dateData);

              descData.push(data.daily[i].weather[0].description);
              setDesc(descData);

              dayFeelData.push(Math.round(data.daily[i].feels_like.day));

              rainData.push(Math.round(data.daily[i].pop * 100));
              setRain(rainData);
            }
          })
          .catch((err) => {
            console.error(err);
          });
      })
      .catch((err) => {
        console.log(err);
      });
  }, []);

  return (
    <div className="flex h-[43.75rem] flex-col items-center justify-evenly">
      {loop.map((i) => (
        <DaysDetails
          key={i}
          date={date[i]}
          desc={desc[i]}
          rain={`${rain[i]}%`}
          dayFeel={`${dayFeel[i]}℃`}
          eveFeel={`${eveFeel[i]}℃`}
        />
      ))}
    </div>
  );
};

export default WeekPage;

pageSwitch in Layout

"use client";

import Link from "next/link";
import { useState } from "react";

const PageSwitcher: React.FC = () => {
  const [page, setPage] = useState("now");

  return (
    <div className="flex justify-center">
      <Link
        href="/"
        onClick={() => setPage("now")}
        className={`flex h-14 w-[11.5rem] items-center justify-center ${page === "now" ? "bg-slate-300" : "bg-inherit"}`}
      >
        NOW
      </Link>
      <Link
        href="/week"
        onClick={() => setPage("7days")}
        className={`flex h-14 w-[11.5rem] items-center justify-center ${page === "7days" ? "bg-slate-300" : "bg-inherit"}`}
      >
        7 DAYS
      </Link>
    </div>
  );
};

export default PageSwitcher;

I think the problem is useEffect dependencies([]), maybe <Link> to page not means the initial render?

I try to link my phone to desktop with USB debug to see real mobile chrome devTool Network page.

mobile devTool-Network page

And compare with desktop devTool-Network page.

desktop devTool-Network page

I just hope it normally fetch data on android like desktop.
Please give me some advice, thanks!
