The WhatsApp web app is not perfect (no software is) but I’ve never had any major issues with it. It’s snappy and very rarely does it glitch out. I find your comment surprising.
It's a ram hog if you stay the tab open for a while, with ton of messages. So from time to time I need to close the tab and open again.
Huge perf issues because of this.
Also had some serious bugs for a few week. Had to let WhatsApp Web wait for completely sync for 15 minutes~ or else it just stop responding and crashes everything.
