Review on 🔵 High-quality 0.91 Inch I2C OLED Display Module - Blue OLED Screen Driver with 2 Pieces, DC 3.3V-5V Compatibility by Tim Paolucci

I wanted to use this for a cloud connected solar temp/humidity meter. I've made several of these. However, this display does not work with the SHT40 sensor. The sensor and display are connected to the I2C bus and you can connect up to 127 devices to the I2C bus, but if I add the standard SSD1306 OLED code from the example in the Arduino IDE, the MCU can do it no longer see SHT40 sensor, says that there is none, and nothing is shown on the display. If I annotate the OLED code SSD1306, the sensor is working fine. This display has no I2C address and is not mentioned in the description. I tried the default 0x3c as well as 0x3d but got nothing. I've never seen the display light up at all, not even the home screen.
