It says it has an update for itself. So you click your notification and it opens Obtainium. It downloads a newer version of its source, builds it for your phone, changes its path to the new one and exits abruptly. When you restart Obtainium it’s the new version with all the same settings. Magic!
Just disabled that through Canta with Shizuku rather than adb on a Samsung Note 20 and rebooted. Should be fine to disable.
