I'm using a Motorola Moto G6 Play and Android 9. When the new app and firmware was recently released I successfully downloaded the app then upgraded the firmware by tapping the gray bar. The steam sound functioned correctly until yesterday. I've been installing and re-installing the micro SD card while working on horn sounds using Audacity on a desktop computer. Before removing card from the DULLHB I've always released the loco, exited the app and unplugged power to the loco.
Yesterday, while starting up with revised 0003.WAV and horn.txt files the app shows the diesel dashboard instead of the steam one like it did before. Re-booting the loco, changing the settings back to the default and uninstalling and reinstalling the app on the phone have not solved the problem. What should I do?
