Yes I know the MG10 has only 2 via USB, I was fully aware of that.
I just bit the bullet this morning & did a factory reset and it’s working now so… Not sure why it wasn’t working before as I just purchased the Ipad Pro 12.9 new last month (for my grand daughter) and it had no apps on it other than GB, Yousician, Final Touch, Animoog & Oddworld.
But either way it’s working now…
