As some of you may know, there are compatibility issues with the Neutrino Element Plus X and Aurora Plus X apps under Android 12/13. Problems include issues with obtaining proper GPS data for speed and direction reporting, an issue with saving relay settings, and most recently with the ability to even download and install the apps on an Android 12/13 device.
The good news is that we're aware of the issues and are working on fixing them. Expect to have these fixes released in 2 weeks or less.
In the meanwhile, if you just need to get around the Play Store's prohibition against even downloading the apps to your device, one of our customers reports success in downloading the app to his computer and transfering it to the phone, where it did indeed install.
