That’s right finally you’re going to be able to login to multiple accounts with Instagram. While this may not be exciting news for many. For those that will use this feature it is huge. For example people who have a personal and work account, or people who manage a website or community.
In a strange twist they are actually rolling this out to Android users first. This doesn’t happen much we are use to getting features after IOS. Even Google does this, for example with Hangouts. So it’s really great to see Instagram giving us a new feature first.
This is showing up in app version 7.12.0 which you can get from APK Mirror or from their Beta Community if you’re a member. However it doesn’t seem to be dependent on the app itself. Even after I downloaded and tried that version I wasn’t able to find it. This must be a cloud roll out and it hasn’t hit all devices quiet yet. In order to find it you’ll have to go into options and scroll all the way to the bottom. There you should find Add Account if it’s been rolled out to you.
