F-Droid and Obtainium fighting to update the same apps is not very user friendly.
Discussion
Very different goals. Set in obtainium to check-only if you prefer F-Droid's (delayed) methodical approach.
Its only delayed for some apps. There are apps that get updates faster from F-Droid. There are also apps that are available on F-Droid but cant be added to Obtainium.
Aurora also updates over obtainium apps
Obtainium or the app's dev aint my friend.
