Many people experience issues with WhatsApp notifications since the iOS 11 update.
IPhone users don’t get notifications for new posts or receive the notifications only after opening WhatsApp.
Although the problem is happening with WhatsApp, it’s likely an issue with iOS or Apple’s Push Notification Service (APNS). Notifications are sent to your phone from Apple’s Push Notification Service (APNS) and the delivery is entirely in control of that service.
Despite we think that the problem is not caused by WhatsApp, we have informed WhatsApp about the many complaints. They will investigate and as soon we learn more, you can read it here or on our Twitter (and Dutch Twitter)
After some contacts with WhatsApp we can report the following:
It’s indeed an iOS 11 bug. It is affecting users who habitually force close their app. This behavior is fairly common among users because of the misconception that apps that appear in the multitasking screen are running in the background. The bug and issues are reported to Apple.
In the meantime WhatsApp is working on an own workaround. They think they have figured out a workaround and are testing it right now. If the test is successful, WhatsApp will release an update to the App Store in a few days.
WhatsApp advises that if you stop force closing the app, your issue shoud also be resolved. Rumours that WhatsApp update 2.17.61 contains the bugfix are not true.
WhatsApp released the bugfix as described in our previous update. Please upgrade to version 2.17.70. Does it fix your notification issues? Let it know in the comments or Twitter (or Dutch account Twitter)
