I think I have found a bug in Autoremote. I am using AutoRemote latest version 3.1.2 and Android 9 on a Samsung Galaxy Note9. The issue seems to be that Autoremote is capable of setting the initial sound of a Notification (Default or 1 to 10) if it hasn't been set before, but it's uncapable of changing it afterwards, meaning setting up a new sound to a specific category that already was assigned a value. No matter how many times your try to change it from the App, the sound will remain the same. A workaround is to uninstall the app completely or at least erase all app data and start over so that the sound can be changed again from the app. Obviously it also works if you change the sound for that category yourself in a manual fashion from the OS itself. Hope this description helps Joao to find the bug and correct it. Thanks Joao!
Hi. On newer android versions you need to change the sounds in Android settings instead of in the app. Unfortunately it's an Android limitation, sorry!
