Diagnostics
What is Diagnostics? It's a feature that allows users to share detailed information about their app usage, crashes, or other issues with the app developers or support teams. This information is typically collected to help troubleshoot problems, identify trends, and improve the app's overall performance and stability. This option is enabled by default, you can disable it.
Bubble
As i said before, you can open bubble chats without even wait for a notification and click on bubble chat button, but you need to know how right?
Sticker Maker
Sticker maker is in experimental right now, so it can't be use.
Paid Features
They said there's a Optional paid subscription, but i can't find any of those options in the app. Maybe this feature is not yet available because the application itself is still in beta. But i guess you can still not concern this, why? cause they said it's Optional, so it may not very useful or worth it to bought.
