It's great to see it being allowed the other way around, although it's a shame it has taken so long.
Originally spotted by WABetaInfo, the 22.2.74 iOS beta has features that suggest it will soon enable users to move their Android chats over to iOS.
It appears that you will an additional app for the feature to function, the app is called Move to iOS.
Since the Move to iOS app isn't available yet, the function does not work in the beta and we don't know exactly when it will release.
WABetaInfo wasn't able to determine supported handsets or operating system versions for the upcoming feature either.
Still, it's a step in the right direction that will allow users who are planning on switching to avoid third-party apps, which could cause privacy concerns.
