This resonates with me, but what caused me to definitively stop using the app was the spam notifications which literally cannot be turned off. That was the last straw of user-hostility that made the app too unpleasant to use. I switched off every last email notification in order to keep that stuff out of my email inbox (nothing less was sufficient to stop it), which made it very easy to permanently ignore the app.

I'm sure the spam notifications A/B tested well for engagement though, /eyeroll.
