Try installing the OneDrive application on the device, then see if you can switch accounts in the OneDrive app to log into each. Then try switching accounts in MobileSheets and see if it will now let you pick the second account. What's weird is that, on my iPad, I have three separate accounts to choose from, and when I tap "Switch OneDrive Account", it shows me a screen that lists all of the accounts and I can just pick the one I want. It saves all the authentication information so I don't even have to enter my password again. If you aren't seeing this, I'm really not sure why, as I've tested this with both a personal account and a business account, and it works the same for both... The UI for picking the accounts and the authentication all goes through Microsoft's library, so it should be working the same way on every device.
