Almost everytime there is a significant fluctuation in my stocks, this app needs to "update" and signs me out. So I completely miss the notifications for days that my stock has increased. Until I manually check. The timing almost seems intentional because it only happens when it's time to notify I made money. By the time I catch it, the spike is over.****Update 3/18/2022**** This app has logged me out and needed an "update" 4 times since the original review in January. Will be changing apps.
