We are talking about a company that makes a crappy product with obvious and blatant limitations (such as not being able to use the same account in different devices, or with different SIMs, or on an iPad, let alone on a PC... and if you have a bad connection messages can arrive out of order - is it so hard to use timestamps? Why are messaging apps getting wrong things that IRC was doing fine back in the 80's?)
Yes, everything they do feels rather sloppy - of course that doesn't stop any of my "normal" friends from almost requiring it for any kind of messaging. A necessary evil in my opinion.
To be honest, I'm not surprised.
