This is the downside of Agile approaches to digital products...setting people (not users) up for a constant flow of "new things" and we get addicted to expecting them, life the ongoing cadence of a new iOS or Android version. Then, when the features become too much for the core, you can't release features and need to fix the core and the consumer doesn't understand this and then expectations start to drop and it's a vicious cycle. Glad you brought up the core issue.
