I just started using an XZ2 switched over from an iPhone. So when I use Instagram, I enable post notifications, and I've noticed that I either won't get notification dots or they'll disappear and I'll only see the latest one (instead of multiple ones saved, unlike YouTube subscriptions dots that stay together) . To be clear, I've got Show all notifications and keep notifications enabled. Is anyone else having this problem, or do I not have my settings correct? Is there an app I can download to remedy this issue?
