I'm a user of a Canon 1300D and I encountered the same behaviour, 1px is missing -> bayers matrice fucked up. I was not aware about this bug and lost 2 entire nights of shots with a clear sky.
With iOS you cannot just install an app like it is possible on Android, you have to install it from the official store or via TestFlight for beta version. I tried right now the beta in its version 2.1.4 tied to the firmware 11.0.5 and sadly the bug is still there. I also have opened an issue. I hope @ZWO will move their ass or create the possibility to have a rollback on firmware version.
