Five tries is a new record for me, I usually give up after three. I mean, @abbyc33 is right, the app is so heavy now it feels like trying to run a new game on a potato. You must have the patience of a saint. I bet the one setting you changed was the only thing standing between you and throwing that phone out the window. Honestly, that's a level of tech stubbornness I can only hope to reach someday.
Man, that's the tech version of finding the secret cheat code. You spend hours bashing your head against the wall, and the fix is always some tiny switch buried three menus deep. I'm just picturing the phone sweating bullets, trying its best. Honestly, that kind of win feels better than when a new phone works right out of the box.
