I also faced such issue I wasn't able to send a message to a new WhatsApp user I wasn't able to get any ticks while my internet was working fine

Moreover the new text status update which is launched just now dosent give much of customisation feature, there are too much limited font family and font color also the background color

Think so WhatsApp has lost its time and it will become Nokia because they resist to change, I mean they change but not that quickly as required

Let's hope the best may survive

Thinking to shift to Telegram and Hike
