Can't get Micro OLED and SD Card Adapter working together on UNO SPI

Am a total newb and am not sure what is going wrong.

Am tyring to use a SparkFun LCD-13003 and a ebay purchased generic MicroSD Card Adapter with a UNO

I want to display a value on the OLED and write that value to a SD Card
With the same wiring set up, am able to write to the serial monitor and OLED if I comment out the SD Card lines.
I am also able to write to the serial monitor and SD Card if I comment out the OLED lines

When I run my code below I get the MicroOLED to display the first text but nothing after than

My Code:

#include <SPI.h>
#include <SD.h>
#include <SFE_MicroOLED.h>

#define PIN_SCK 13
#define PIN_MISO 12
#define PIN_MOSI 11
#define PIN_RESET 9
#define PIN_DC 8
#define PIN_CS_SD 6
#define PIN_CS_OLED 5

File MyTest;

MicroOLED oled(PIN_RESET, PIN_DC, PIN_CS_OLED);
int mycounter = 1;

void setup() {
Serial.begin(9600);

if (SD.begin(PIN_CS_SD)) {
Serial.println(“SD card is ready to use.”);
} else {
Serial.println(“SD card initialization failed”);
delay(100);
exit(0);
}

digitalWrite(PIN_CS_OLED,HIGH);
digitalWrite(PIN_CS_SD,LOW);

MyTest = SD.open(“MyTest.txt”, FILE_WRITE);
MyTest.print("Count = ");
MyTest.println(mycounter);
MyTest.close();

digitalWrite(PIN_CS_SD,HIGH);
digitalWrite(PIN_CS_OLED,LOW);

oled.begin();
oled.clear(PAGE);
oled.setFontType(0);
oled.setCursor(0, 0);
oled.print(“mycounter”);
oled.display();
delay(1000);
oled.clear(PAGE);

digitalWrite(PIN_CS_OLED,HIGH);

Serial.print("Count = ");
Serial.println(mycounter);
}

void loop() {

mycounter = mycounter+1;

digitalWrite(PIN_CS_SD,LOW);

MyTest = SD.open(“MyTest.txt”, FILE_WRITE);
MyTest.print("Count = ");
MyTest.println(mycounter);
MyTest.close();

digitalWrite(PIN_CS_SD,HIGH);
digitalWrite(PIN_CS_OLED,LOW);

oled.clear(PAGE);
oled.setFontType(0);
oled.setCursor(0, 0);
oled.display();
delay(1000);
oled.clear(PAGE);

digitalWrite(PIN_CS_OLED,HIGH);

Serial.print("Count = ");
Serial.println(mycounter);
}

problem is the MISO-line. Many SD-modules doesn't release the line as is should. Hardware fix possible. Several posts in this forum discusses same problem
