what I hate is that for every update all the linked devices get logged out and if you don't have good camera orientation skills it'll be sort of hard to(say for example) link an android tablet to your whatsapp. because you have to scan the QR code for it. Hense why I have to use seeing AI for that (or try to)
I find no problems with the QR code. There's usually more than one option, so if one doesn't work the other should. There's also a code one can get and I have had to use that method, but the last couple times the QR code worked flawlessly.
It works fine for me. For those who don't know, there is an NVDA add-on called WhatsApp Desktop Enhancer, that add-on really helps accessibility of the app. You can find the add-on in the NVDA add-on store.
