Meta is testing two features that integrate Facebook and Instagram more closely together. On Monday, the company began rolling out a new interface on Android, iOS and on the web for switching between accounts. Provided you’ve added your Facebook and Instagram credentials to the same Accounts Center, you can use the feature to switch between the two apps without navigating to your phone’s home screen, multitasking menu or app drawer. The interface also allows you to see a count of all your notifications in one place.At the same time, Meta is introducing a redesigned login and onboarding experience on Android and iOS. If you’re new to the company’s social networks, you can create one account and then use it to create additional ones. For those who already have both Facebook and Instagram accounts, it’s now possible to use the login information associated with one app to access the other – though you first need to add them to the same Accounts Center.MetaMeta will notify you e
