Thingy:91 app not update

[Sobiso]

Hi all

I have problem with uploading app to this module. On Mqtt_simple I added 

CONFIG_BOOTLOADER_MCUBOOT=y

Compile program in Segger and i got app_signed.hex. Im using nrf Programmer. Power on with pushed SW4, uploaded software (app_signed.hex) and after that I have still old program (nrf cloud connect). What Im doing wrong ? On LTE Link Monitor I don't see any serial port.
