Okay, I just tried using Live caption on my iPhone SE2, and the NLS EReader made by Humanware. and I was stopped by the statement, "Unsupported language or region." Now I did check my general settings and my preferred language is English, and region is US, which would make sense, since that's where I live. However, that's the statement I get, when trying to run this thing. All the other choices seem to work just fine. So, not sure if it's a situation where the NLS EReader is not being supported or not. A friend of mine is using a Mantis q40, and of course that works just fine, as has been acknowledged and publicized everywhere. So, maybe this was a limitation imposed here, or maybe it does not work with anything but 40 cell devices. Color me confused.
