Well, I saw this in the beta here and Samsung didn't do anything
Ok, I deleted cache and data of Modes and Routines, turn off phone, wiped cache through recovery mode, turn phone on and opened Modes and Routines.
When the loading finished after a minute, I tapped the three dots up, settings, and turned on "add to app screen." I didn't close Modes and Routines, the open tab remained in Recent, and when I tapped the icon on the app screen, Routines automatically opened and all the settings "if-than" were back.
Now I must set up all my Routines again
