We heard that Facebook and WhatsApp were planning an iPad version of the popular messaging app more than a year ago, but we’re still waiting for it to arrive. The trail has been rather cold in recent months as well, suggesting the project might have stalled.

Now, according to a new report, the reason for that is simple – there’s currently no support within WhatsApp that would allow two devices to be linked to the same account.

Currently, WhatsApp accounts are linked to phone numbers and can only be used on the device that a given phone number is linked to. That means iPads are out of luck unless they use the somewhat less-than-ideal web interface. According to a new report by WABetaInfo, it’s that lack of multi-account support that’s causing problems.

WhatsApp is working on the possibility to use the same account on different devices. Actually they are testing the feature in order to work with 4 devices at the same time.

When the user wants to use WhatsApp on a second device, there is the need to copy the chat history. In this case WhatsApp always requires a Wi-Fi connection, because it may use a large amount of your data plan

When WhatsApp has safely copied the chat history to the second device, it will be finally possible to use your account from it. Note that any message will be delivered to all your family devices, so your chat history will be always synced across platforms.

WhatsApp has also developed an iPad app, that will be released after the activation of the feature, so you will be able to use WhatsApp on your iPhone and your iPad at the same time.

The problem of keeping chat histories synced across multiple devices is one that Apple continues to struggle with. Plenty of people still find that messages are missing when they switch iMessage use from iPhone to iPad to Mac. Hopefully Facebook’s knowledge of the process with Facebook Messenger will stand WhatsApp in good stead here.
