Last November, WhatsApp introduced messages that disappear after seven days. A couple of months ago it also started work on "view once" messages, that are gone forever after you viewed them once, as the name handily implies.

Now it turns out that WhatsApp is also going to add another option for message expiry, and that's 90 days. So whenever all of these features make it out of beta, you'll be presented with a menu similar to the one you can see in the screenshot below, where you'll be able to pick between "Off" (so messages never disappear), or choose to have your chats disappear after 24 hours, 7 days, or 90 days.

That's a lot of flexibility, but the "90 days" option has only now made it to the WhatsApp Android beta (spotted in the latest version, 2.21.9.6). 

WhatsApp sometimes keeps upcoming features in the beta realm for many weeks (and even months) before finally releasing them to all of its users, so we don't yet know when you should expect this to arrive for everyone. Still, it's good to know that it's being worked on.

WhatsApp for iOS to launch large previews when sharing links

In April, WhatsApp rolled out an update with an improved media preview. Now, the app is testing a large preview when sharing links. According to the reliable WABetainfo, with WhatsApp beta for iOS 2.21.160.17 available on TestFlight, all beta testers can see large previews when sharing links with this update. 

If you’re enrolled with WhatsApp’s beta program and you update your app, just try sending a link to a chat to discover a larger preview.

Not only that, but the latest betas also bring the ability to transfer messages between iPhone and Android, as reported by 9to5Google.

Once it’s reached your device, in the “Chats” settings of the app, you’ll find a new “Move chats to Android” option.

However, for now, the option doesn’t seem to be functional as of yet. The current belief is that it may require the “Switch to Android” app for iOS, or perhaps an updated version of Google’s Data Restore Tool on a Samsung phone.

Most importantly, with WhatsApp rolling out these features, it might indicate that the app is readying the ability to have the same account running on multiple devices.

Multi-device support is one of the top features WhatsApp users want. When it’s available to all users, people will be able to use WhatsApp on four different devices and one mobile phone, which means you’ll be able to use the app on a Mac even without your iPhone on or connected to the internet.

With multi-device compatibility, users will be able to use WhatsApp Web, desktop version, and Portal without an internet connection or the user’s main phone.
