Can't get MKR GSM 1400 working with MKR MEM SHIELD

Hi,

I can't get working even simplest CardInfo example from SD library with my MKR GSM 1400 working with MKR MEM shield.
All I get is initialization error. Do I need to change anything else than setting chipSelect to 4?
SD card seems to be fine as it works on my computer.

I've finally managed to get it working. Problem seems to be related with SD card, not the shield. With different card it worked just fine.
