In the past, if you wanted to share a tweet on Instagram, you would usually need to take a screenshot of that tweet and post it either on your feed or in your Instagram Stories. This is a bit of a long-winded method and you might end up with a bunch of screenshots taking up space on your phone.
However, the good news is that if you tend to share tweets on your Stories quite often, Twitter has announced that screenshots are no longer necessary. The company has revealed that users will now be able to share tweets directly to their Instagram Stories, although for now it seems that this is a feature that is exclusive to iOS devices, but we imagine it will eventually make its way onto Android later on.

That being said, it should be noted that this only lets users share to Instagram Stories and not to Instagram itself, so if you wanted to share it in your profile, the screenshot method seems to be the only way. The feature should already be rolling out to users at this time of posting, but don’t worry if you don’t see it yet as it should eventually be available to you. You should also make sure to have the latest version of Twitter if you’d like to make sure to have all the latest features.
