whatsapp web on ipad can't be opened

I was able to solve this problem by turning off the “Request Desktop Website” for all websites in Safari setting in Settings app. Once I turned off this setting, everything started working as it used to before I updated my iPad to iOS 15.7. Firefox worked too, but I didn’t want yet another web browser app on my iPad. I am comfortable with Safari.

Safari is an integral element of iOS/iPadOS - and cannot be updated independently of the OS. 

If your iPad has been updated to the most recent version supported by your iPad, then Safari is as up-to-date as is possible.

However, some websites may incorrectly identify your iOS/iPadOS Safari User Agent when used in one or other of its browsing modes - of which their are two - these being Desktop and Mobile. It’s easy to switch between modes if a website isn’t functioning correctly. From the desired web-page, touch the aA icon at the left of the Address Bar; this will reveal a menu. From the menu select Website Settings, then select (or deselect) Request Desktop Website, then tap Done. Now refresh the webpage.

The chosen setting will be saved for the selected website - and can be simply reversed if needed.

Same issue here. I was able to use web.whatsapp with firefox.

I installed Firefox app, working 👏👏👏

LotusPilot's solution is the only solution that worked like a charm. I am using the latest version IOS 15.7 (I needed to hit "request mobile website")

This was great, thanks!!

I was able to login with no issues. I set firefox as my default browser and was able to scan the QR code. No issues now, though it sucks that you can’t use safari for WhatsApp.

Hello! I had the same issue today… I tried to use Firefox browser app and still works.

Feel free to check it, today Firefox saved my life :)

I hope someone can fix safari again but for now we have the solution to this.

Install Firefox app, works

Read the comments, get Firefox app, WORKS

Thank you. It worked. But it works only when i opt for “request mobile website”. Desktop version doesn’t work.

After the update to 15.7 WhatsApp does not work with Safari, Chrome or Opera, only with Firefox everything is ok!

It works with Firefox.

Firefox is the solution.

Have the same problem, Firefox helps.

Maybe problematic if the IPhone is on IOS 16 and IPad on IPadOS 15.7?!
