Anyone has issue with whatsapp in phone and PC. The messages sent, both were not sync each others.

What I sent via Whatsapp in phone can't be seen in Whatsapp PC ver or vice versa.

Another issue:

1. Business account users who sent me messages, only 1 tick and I can't receive at all.

I gave up using the WA PC app. It'll just say internet not connected despite PC reboot or restarting app. The only way to get it working again is to do a fresh reinstall. Now just using WA on web browser.
