Decrease Voltage Arduino IoT Cloud


I am using Arduino MKR 1010 WiFi. I try to develop a program controlling 8 relays. I try to configure output pins generating voltages from 3 to 5 V. With this board I can set voltages up to 3.3 V. I realized that when I use Arduino IoT Cloud the voltage is decreasing to 2.2 V. Is it normal or I am wrong? When I program the board without using IoT cloud everything is normal. For control of the relays I need 3.3 V. How to overcome this problem? Please help!
