I hear the same about people's Telegram installations. I guess they're not using these 'alternative messengers' daily and very quickly the apps' services are switched into permanent hibernation and aren't loaded on boot. That means more negative experience which eliminate the appetite for an anything but good old WhatsApp for good. I found that the modern normie has absolutely no clue what's happening in their phones to the point they don't ever enter the settings. Talking about pretty much every age range at this point, I work with a lot of people from all generations.
