Ok, here’s my update: I browsed the Android folders hoping to find the stored presets and save them but the H9 Control data folder is empty. I guess the presets are stored in some system file or whatever out of my limited knowledge. So I ended up erasing the app and installing the 4.0.1 provided by the Eventide support and it seems to be working again. Will have to do a lot of tweaking these next few days so will update this post if any further problem occurs
