Was this issue ever resolved. I am getting the same error when attempting to follow/unfollow users. My keys are auto-generated from Fabric. I am able to follow and un-follow once, and then my second attempt I get the “invalid or expired token” error. I can then logout and log back in, and do the same thing. Works first time, error second time. My other testers have not been experiencing this problem. Its only with my account and keys. I even regenerated my keys with Fabric and changed them in my application. Any help? @bonnell
