Fresh Install and even the simplest of code will not compile

[gnfontaine]

I am using a ESP8266 ESP-12 ESP-12F NodeMcu Mini Module and SoftAP works fine without the autoconnect Library.
I tried the simple example and just including the library and errors out with the following code.
Confused

#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <AutoConnect.h>

ESP8266WebServer server(80);
void setup() {}
void loop() {}

I installed older version and works in Arduino Ver 1.8.19 however would be nice if worked in version 2+

Same with esp32 and Arduino Version: 2.3.3-nightly-20240423
Date: 2024-04-23T03:11:06.602Z
CLI Version: 0.36.0-rc.1

I used the most simple example from "Getting started"

Just need to change the HTTPClient, there is a typo in HTTPUpdate.h, which makes it call the new library instead of the old one. Making that change made it work for me.
