A question: Is it normal that the boot time from powered-off state to lockscreen menu takes about 33seconds using sx core? When I press the power button, the blue light gets green after 1-2 seconds and goes fast from SX OS Logo to the nintendo logo. But from Nintendo logo and to the lockscreen menu, it takes long. (From Nintendo logo to Joy-Con logo it took 16 seconds). The entire boot time is always between 30-35 seconds. I have hidden-partition based emunand on SD-Card from Sandisk Extreme 128GB rated with A2 C3 V30 UHS-I U3 formatted as FAT32 using guiformat. Tried to test the speed of the sd card and it reaches the speed as provided from the manufacture.
Edit: My friends Switch takes about 15-20 second to boot from powered-off state to lockscreen menu.
it might sound silly but next power on try to hold down the power button until you see the green light, give it a go and let us know how it goes
