I installed the MirrorGo (Stream & Recorder) app from the playstore to try but uninstalled it over privacy concerns in my android 10. Everything looks fine but recently I discovered it still left some traces in the device. When I checked the virtual keyboards in Language & input settings, I found the MirrorGo keyboard is still available. I tried checking the list of all apps on the mobile and couldn't find anything related to that. How do I remove that from my device?
