I just restored my whatsapp back up in my iPhone that using iOS 26. But now whatsapp is very slow, even feel so hard to scroll in that application. I've already back up and restore it again, but still too slow. Whatsapp support team said that it is because the iOS problem. What should i do?
iPhone 17, iOS 26
Just an option to consider. Do you have a lot of data? Give it a few days and let it all catch up. If you don't have background app refresh turned on for example, all that data might be trying to download to your phone while you are using the app and that can cause sluggishness because of your connection?
My assumption here is if this is the only app that is working slow, its definitely whatsapp. Consider not trying to download all the data at once and only retrieve the data you need when you need it. That way you can slowly get all of it back over time.
Also what service did you use to back up the data? Google drive can infamously, at times, be very slow moving.
Meta is responsible for fixing issues with their software, not Apple. You will need to contact Meta for help with their software, this is not an Apple product.
Here are a couple of ways to contact them -
