This issue is happening only in mojave while fro a fresh install in sierra its causing no such issue. WhatsApp on Mac promises the smoothest messaging and VoIP experience for these operating systems: Windows 8.1+,macOS X 10.9, Android OS 4.03+, and iPhone iOS 8+. So that we are made aware that we have the access to the chats in a very limitted manner. Since I wouldnt want to lose the option to acess my older chats, files on whatsapp on mac, I would like you to please look into this issue and address it even if you aren't able to fix it as soon as possible. The other option thats being displayed is that of 'LOG OUT' which I simply can not, as If I do so then I would lose acess to my older whatsapp chats on my mac (which I still need ), thanks to this multi-device feature which ALLOWS US TO ACCESS SOME OF OUR CHATS On multi device BUT STRIPS AWAY the ability to acess chats past a particular time. Link up to 4 devices and multiple phones. Alternatively, you can go to the Mac App Store and find the app by looking up WhatsApp Desktop Mac. Download WhatsApp for Windows and Mac - WhatsApp desktop app makes your Windows/Mac the ultimate messaging machine.

I don't understand whta improvements and bug fixes have been made by you, the app is always stuck 'at connecting to whatsapp' and after some time shows the message 'make sure your computer has an active internet connection' even though I have decent internet connection as a session of the whatsapp web is still working on my browser(safari). To install WhatsApp for Mac, you can download the app from the WhatsApp website.

I don't know what improvements have been made.
