Are you sure cause this was fixed a while back, what esp32 version you using ?
Working for me on stable.

Sounds more like you are on an old esp32 version, this was changed in 2.5.2 I think

How does that versioning relate to the esp32? I tried it on 1.0.4 and 1.0.3 of the arduino core for esp32

I just tried.
Esp8266 on 2.7.1, no issues
Esp32 on 1.0.4 shows that issue

So is this an issue with the arduino core then?

not sure you said you are using develop branch of wm and its up to date ?

I will try to reproduce on arduino , I only use platformio.

can you look in strings.h and make sure it matches the struct ?

const wifi_country_t WM_COUNTRY_US{"US",1,11,CONFIG_ESP32_PHY_MAX_TX_POWER,WIFI_COUNTRY_POLICY_AUTO};

if we are talking about strings_en.h yes it matches that.
Interestingly though, if I comment out the if statement so that both the esp8266 and esp32 use the version intended for the ESP8266 it doesn't throw that error.

const wifi_country_t WM_COUNTRY_US{"US",1,11,WIFI_COUNTRY_POLICY_AUTO};

After that I'm only left with the error:
Documents/Arduino/libraries/WiFiManager/WiFiManager.h:357:5: error: 'wifi_event_id_t' does not name a type wifi_event_id_t wm_event_id; ^

you are missing the same argument count
CONFIG_ESP32_PHY_MAX_TX_POWER

so esp ver must be old, are you sure you do not have a boards url set in prefs?

ok, my bad. I get it now. I didn't understand what it meant with esp32 with staging. I manually reinstalled the esp32 into arduino using the manual method on the development branch, and it works.

Sorry to waste your time.

Yeah if you use staging you have to manually update it via git or download. Its bleeding edge unstable code
