I am trying to write to the adafruit display using Arduino MKR1500 when it is connected to the internet. The issue I am facing is when I add the code to connect to the cloud, the display stops working. If I removed that piece of code, the display outputs correctly. As of now I am just printing "hello world" on the screen. Below is the code without the cloud connection:
/**************************************************************************
This is a library for several Adafruit displays based on ST77* drivers.

as well as Adafruit raw 1.8" TFT display

Check out the links above for our tutorials and wiring diagrams.
These displays use SPI to communicate, 4 or 5 pins are required to
interface (RST is optional).
