Remote input in the Android application should respect the touchpad settings in system settings. For example, natural / reverse scrolling. Reproducible: Always
There is an option to change the direction in the Android app, but we decided to make it independent of the desktop config on purpose so it's not a bug.
Sorry, I didn't know those settings existed. I just found them (for those wondering, in the app, tap the three dots> Plugin Settings> Click the button on the far right hand side of "Remote Input"> Check "Reverse Scrolling Direction"). Thanks.
