I'm unable to link to my Facebook account. After I enter my FB username and password, Instagram processes it for a bit, then the password section goes blank. I've double and triple checked to make sure I'm using the correct username/password combination, so it's not me. Help!
Unfortunately, in V1.0, we have a bug that causes Instagram to crash when trying to connect to third-party services such as Facebook if the password you're using contains an ampersand (&). For now, if you're using an ampersand in your password, you'll need to change your password on that service before you can connect with it through Instagram.
If that issue doesn't seem to be the problem, there have been some temporary issues with the Facebook API (which is how Instagram is able to "talk" with Facebook) that we hope will be resolved shortly. Thanks for understanding.
