At Facebook Messenger for IOS my messages to some friends (doesn?t happen to all, what is even odder!) are showing the sent symbol (the blue circle with a check mark), that NEVER is replaced by the indication of delivered message (the circle with blue fill with a mark of check). Therefore, I am always in doubt whether they have received them or not, whether they have read it or not, etc ...
Then, I end up confirming that, some of the messages they receive, some not!
However, the symbol never changes, always keeping the indication of ?message sent? until receiving a reply. And then, when I send a new message, everything is repeated over and over and over.
And, when i check those messages in Facebook, also I don't get the "Viewed at..." message information. It's like if the message is lost between the send act and the receiving act...
