I'm having trouble connecting to Twitter.
In most cases where people can't log into Twitter, there's a temporary outage on Twitter's end. Usually these login issues are resolved within a few hours. If the issue has lasted more than a few hours, try relinking your Twitter and Instagram accounts:
- Go to your profile and tap (iOS) or (Android) in the top right.
- Tap Linked Accounts > Twitter.
- Tap Unlink, then tap Twitter and re-enter your login info.
