I'm updating from my old IPAD to a more recent IPAD. I'm deciding between the IPAD Air and the IPAD Pro. I'd be interested in recommendations. Also I'd seen somewhere that the Desktop version of LOGOS can be installed on the IPAD Pro. I spoke with LOGOS support team and they would only indicate that the OS version needed to be OS 16.4 or higher. The LOGOS support team indicated only that the Desktop version of LOGOS was not designed for mobile devices.
