At least they tell you about it - there's a banner on the top of the app. Last time WhatsApp was having issues, it didn't give any indication - messages just weren't being delivered (but as a user, there's no way to distinguish between "no messages" and "messages not being delivered").
I don't see a banner on the top of my app. I only found out when the desktop client kept timing out with 502 errors and after asking on Twitter, found other people were having issues too.
For me it's the other way around, haven't had any banners or anything on Android, whereas the desktop client has, and messages have been throwing 50x errors, while the mobile messages just seem to take ages to send.
The desktop app shows a yellow "DISCONNECTED - Check your network connection" warning. They probably should work on better error/status reporting in next version.
Last time WhatsApp was having issues, a “Connecting” banner was shown permanently on the app and all outgoing messages displayed a clock instead of a tick, showing that they weren’t reaching the server.
I'm not getting a banner on iOS either, however when I try to send a message it fails with a red exclamation mark in a circle saying "Request failed: service unavailable (503)"
Edit: A few minutes after the message failed to send I got a yellow banner stating that the service was experience interruptions.
However the banner disappeared shortly afterward, so it would have been easy to miss.
heavy user of whatsapp and I can't recall having any issues with whatsapp ever. I'm a heavy user of signal as well and... it's a bit crap honestly. I actually needed to transfer a file to a client today and was strongly relying on signal for that...
