Arduino Uno R4 Wifi and WiFiClientSecure

Thanks for your answers. The library I’m trying to use is this one Salesforce - Arduino Reference.

I tried changing the board to ESP32 - Arduino Nano and it compiles without problems so I think i have to find a workaround (maybe implementing everything by scratch as I will use some POST and GET APIs).

I have some experience with ArduinoHttpClient which worked fine in past for me when everything was in HTTP, I hope I won’t face a lot of problems when working with HTTPS
