Lots of bugs lately: Replied to a message. Later on when I opened the messenger my reply disappeared (not like if it was unsent - that usually is showing in a messenger), moreover the message I replied to is showing as Unread. Awkward. Another e.g.: Sent a happy birthday wish to another contact - it's not even there, as if if I never did. Upsetting, as not only I've spent time preparing a wish, but it looks like birthday was forgotten to that person.
