I paid for premium to get access to SD card using USB otg. But it doesn't work! Don't know why it doesn't work in my case, but apparently the feature is limited, which I only found out later reading the Play Store description, not a word about limitations when using the free version and when it suggests to pay! Used with Samsung Galaxy Tab S8 Ultra, Android 12, 128 GB SD card formatted in Nikon D850. UPDATE: So be honest and tell about the restriction openly!
