The functionality of WhatsApp on millions of iPhones is soon to end.
Soon, many iPhone users who wish to keep using WhatsApp will have to upgrade their gadgets.
Anyone who has an iPhone 5, or any previous Apple handset, is in for some terrible news.
It makes commercial sense to stop delivering updates when phones get older because fewer people are using them.
This is bad news for anyone with an iPhone 5, or any earlier versions of the Apple device.
"Devices and software change frequently, so we routinely assess what operating systems we support and release upgrades," WhatsApp stated.
"Like other technology firms, we evaluate which hardware and software are the oldest and have the fewest users each year to determine what to stop maintaining.
Additionally, these gadgets could not be up to date on security patches or might not have the features necessary to run WhatsApp."
