 Who knows. I didn't do a lot of research before making this. It was fun making it.
 
 ## Can I use this in my app? Will it stay free?
-Yes. As long as you don't abuse it, it'll be available and free of charge. I do not plan on monetizing
-the service.
+Yes. As long as you don't abuse it, it'll be available and free of charge. While I will always allow usage of the ntfy.sh
+server without signup and free of charge, I may also offer paid plans in the future.
 
 ## What are the uptime guarantees?
 Best effort. 
 
+ntfy currently runs on a single DigitalOcean droplet, without any scale out strategy or redundancies. When the time comes,
+I'll add scale out features, but for now it is what it is.
+
+In the first year of its life, and to this day (Dec'22), ntfy had **no outages** that I can remember. Other than short 
+blips and some HTTP 500 spikes, it has been rock solid.   
+
+There is a [status page](https://ntfy.statuspage.io/) which is updated based on some automated checks via the amazingly 
+awesome [healthchecks.io](https://healthchecks.io/) (_no affiliation, just a fan_).

 ## What happens if there are multiple subscribers to the same topic?
 As per usual with pub-sub, all subscribers receive notifications if they are subscribed to a topic.

+## Can you implement feature X?
+Yes, maybe. Check out [existing GitHub issues](https://github.com/binwiederhier/ntfy/issues) to see if somebody else had

+## I'm having issues with iOS, can you help? The iOS app is behind compared to the Android app, can you fix that?
+The iOS is very bare bones and quite frankly a little buggy. I wanted to get something out the door to make the iOS users
+happy, but halfway through I got frustrated with iOS development and paused development. I will eventually get back to
+it, or hopefully, somebody else will come along and help out. Please review the [known issues](known-issues.md) for details.

 ## Can I disable the web app? Can I protect it with a login screen?
 The web app is a static website without a backend (other than the ntfy API). All data is stored locally in the browser
 cache and local storage. That means it does not need to be protected with a login screen, and it poses no additional

+# Known issues
+This is an incomplete list of known issues with the ntfy server, Android app, and iOS app. You can find a complete
+list [on GitHub](https://github.com/binwiederhier/ntfy/labels/%F0%9F%AA%B2%20bug), but I thought it may be helpful
+to have the prominent ones here to link to.

+## iOS app not refreshing (see [#267](https://github.com/binwiederhier/ntfy/issues/267))
+For some (many?) users, the iOS app is not refreshing the view when new notifications come in. Until you manually
+swipe down, you do not see the newly arrived messages, even though the popup appeared before.
+
+This is caused by some weirdness between the Notification Service Extension (NSE), SwiftUI and Core Data. I am entirely
+clueless on how to fix it, sadly, as it is ephemeral and now clear to me what is causing it.
+
+Please send experienced iOS developers my way to help me figure this out.
+
+## iOS app not receiving notifications (anymore)
+If notifications do not show up at all anymore, there are a few causes for it (that I know of):
+
+**Firebase+APNS are being weird and buggy**:    
+If this is the case, usually it helps to **remove the topic/subscription and re-add it**. That will force Firebase to 
+re-subscribe to the Firebase topic.
+
+**Self-hosted only: No `upstream-base-url` set, or `base-url` mismatch**:   
+To make self-hosted servers work with the iOS
+app, I had to do some horrible things (see [iOS instant notifications](config.md#ios-instant-notifications) for details).
+Be sure that in your selfhosted server:
+
+* Set `upstream-base-url: "https://ntfy.sh"` (**not your own hostname!**)
+* Ensure that the URL you set in `base-url` **matches exactly** what you set the Default Server in iOS to
