According to specs, it should handle up to 256gb using SIM 2 slot.
Make sure the SD card is preformatted to FAT32 or ExFat.
You can do this using a computer or the Settings --> Storage option on the phone.
The smartphone is reading or writing on the memory card. And it is taking time, hence it shows SD card is busy.
