I imagine there are a lot of stories like that from the "everything needs to be a mobile app" era.

So many companies invested vast engineering resources in building out iOS/Android apps only to later find that their users only interact with their tool once every few weeks, which wasn't often enough for them to earn a place in that relatively tiny list of a few dozen apps that any one individual actually uses.

For many users with cheaper phones asking them to install your app is asking them to pick which of their photos they're going to delete to make space for it!
